The authors reviewed the initial chest roentgenograms of 182 consecutive adult patients with proven active tuberculosis. Less than 50% of all cases were known or suspected at the time of initial presentation. There is a low degree of correlation between radiologically discernible active pulmonary tuberculosis and extrapulmonary tuberculosis. A high percentage of cases represent uncommon pulmonary locations. The frequency of occurrence of four common pulmonary patterns is presented. 21 references, 4 figures, 5 tables

Objective: To evaluate the HRCT findings of early/active pulmonary tuberculosis before and after antituberculous chemotherapy. Methods: One hundred tuberculous patients were studied prospectively and they were divided into 2 groups according to the history. The diagnosis of early active pulmonary tuberculosis was based on positive acid-fast bacilli in sputum (75 patients) and changes on serial radiographs obtained during treatment (25 patients). The correlation between pathology and imaging was done in the lungs from the cadavers of five other patients who died of pulmonary tuberculosis. Results: Comparing with the presence of other HRCT findings, the presence of centrilobular lesions (93.0%), tree-in-bud appearance (76.0%), and wall thickening of bronchioles (70.0%) were most common signs in both the first group consisting of 66 patients with newly diagnosed pulmonary tuberculosis and the second group consisting of 34 patients with recent reactivation of pulmonary tuberculosis at examination by HRCT, and there was significant difference between the presence of those signs and other signs (P<0.001). Conclusion: Centrilobular lesion appeared to be the most commonly seen characteristic HRCT features of early active tuberculosis, and it may be helpful to the diagnosis and (or ) differential diagnosis if combined with other commonly seen characteristic HRCT features as well as clinical information

This study investigated whether there was an association between splenectomy and pulmonary tuberculosis. This was a case-control study using the database of the Taiwan National Health Insurance Programme. We identified 18 960 patients (aged 20 years or older) with newly diagnosed pulmonary tuberculosis as the case group and 73 988 participants without pulmonary tuberculosis as the control group from 1998 to 2011. Both groups were matched for sex, age (per 5 years) and index year of pulmonary tuberculosis diagnosis. The risk of pulmonary tuberculosis associated with splenectomy and other co-morbidities was estimated. After controlling for confounders, multivariable logistic regression analysis showed that the odds of pulmonary tuberculosis were 1.91 in patients with splenectomy (95% CI 1.06-3.44), compared with the participants without splenectomy. Chronic obstructive pulmonary diseases (OR 3.07, 95% CI 2.94-3.21), pneumoconiosis (OR 2.20, 95% CI 1.90-2.56), chronic kidney diseases (OR 1.49, 95% CI 1.33-1.67), diabetes mellitus (OR 1.57, 95% CI 1.50-1.64) and chronic liver diseases (OR 1.31, 95% CI 1.25-1.37) were associated with an increased risk of pulmonary tuberculosis. The sub-analysis demonstrated that the odds of pulmonary tuberculosis were 4.81 (95% CI 2.31-10.0) for patients co-morbid with splenectomy and any of the above diseases. Splenectomy is associated with a 1.9-fold increased risk of pulmonary tuberculosis in Taiwan. There is a synergistic effect between splenectomy and other co-morbidities on the risk of pulmonary tuberculosis. © 2013 The Authors Clinical Microbiology and Infection © 2013 European Society of Clinical Microbiology and Infectious Diseases.

Candida species are emerging as a potentially pathogenic fungus in patients with broncho-pulmonary diseases. The synergistic growth promoting association of Candida and Mycobacterium tuberculosis has raised increased concern for studying the various Candida spp . and its significance in pulmonary tuberculosis patients during current years. This study was undertaken with the objective of discovering the prevalence of co-infection caused by different Candida species in patients with pulmonary tuberculosis. A total of 75 patients with pulmonary tuberculosis diagnosed by sputum Ziehl-Neelsen staining were included in the study. Candida co-infection was confirmed using the Kahanpaa et al. criteria. Candida species were identified using gram stain morphology, germ tube formation, morphology on cornmeal agar with Tween-80, sugar fermentation tests and HiCrome Candida Agar. Candida co-infection was observed in 30 (40%) of patients with pulmonary tuberculosis. Candida albicans was the most common isolate observed in 50% of the patients with co-infection, followed by C. tropicalis (20%) and C. glabrata (20%). Candida co-infection was found in 62.5% of female patients, while it was observed in only 29.4% of the male patients (P value 0.0133). Mean ± SD age of the patients with C. glabrata infection was 65.83 ± 3.19, while the mean ± SD age of the patients with other Candida infections was 43.25 ± 20.44 (P value 0.0138). Many patients with pulmonary tuberculosis have co-infection with Candida spp. The prevalence of non-albicans Candida species is increasing and may be associated with inadequate response to anti-tubercular drugs. C. glabrata infection has a strong association with old age.

We evaluated the value of CT-guided transthoracic core biopsy for the diagnosis of mycobacterial pulmonary nodules. The 30 subjects in this study had pulmonary nodules that had been either diagnosed histopathologically as tuberculosis or were suspected as tuberculosis based on a specimen obtained by CT-guided transthoracic core biopsy. The histopathological findings, the existence of acid-fast bacilli in the biopsy specimens, and the clinical course of the patients after the biopsy were reviewed retrospectively. Two of the three histological findings for tuberculosis that included epithelioid cells, multinucleated giant cells and caseous necrosis were observed in 21 of the nodules which were therefore diagnosed as histological tuberculosis. Six of these 21 nodules were positive for acid-fast bacilli, confirming the diagnosis of tuberculosis. Thirteen of the 21 nodules did not contain acid-fast bacilli but decreased in size in response to antituberculous treatment and were therefore diagnosed as clinical tuberculosis. Seven nodules with only caseous necrosis were diagnosed as suspected tuberculosis, with a final diagnosis of tuberculosis being made in 4 of the nodules and a diagnosis of old tuberculosis in 2 nodules. Two nodules with only multinucleated giant cells were diagnosed as suspected tuberculosis with 1 of these nodules being diagnosed finally as tuberculosis and the other nodule as a nonspecific granuloma. When any two of the three following histopathological findings - epithelioid cells, multinucleated giant cells or caseous necrosis - are observed in a specimen obtained by CT-guided transthoracic core biopsy, the diagnosis of tuberculosis can be established without the detection of acid-fast bacilli or Mycobacterium tuberculosis

Full Text Available OBJECTIVE: To determine the prevalence of nutritional deficiency among patients with pulmonary tuberculosis. METHODS: This was a cross-sectional study using data obtained from the Brazilian Case Registry Database and from the medical records of patients diagnosed with pulmonary tuberculosis (15-59 years of age residing in one of the municipalities that make up the 16th Regional Health District of the state of Bahia. We calculated the incidence, lethality, and mortality rates, as well as the prevalence of nutritional deficiency, as evaluated by body mass index. Demographic, social, clinical, and epidemiological data were collected. RESULTS: Of the 72 confirmed cases of tuberculosis, 59 (81.9% were in males, and 21 (29.2% of the patients were in the 40-49 year age bracket. The majority (85.3% described themselves as Mulatto or Black; 55.2% reported using alcohol; and approximately 90% were treated as outpatients. In the district and age bracket studied, the incidence of pulmonary tuberculosis was 30.6/100,000 population. Among the 72 patients, data regarding nutritional status was available for 34. Of those, 50% and 25%, respectively, presented nutritional deficiency at the beginning and at the end of treatment. No statistically significant differences were found between normal-weight and malnourished patients regarding the characteristics studied. CONCLUSIONS: The prevalence of nutritional deficiency was high among our sample of patients with pulmonary tuberculosis. This underscores the importance of nutritional follow-up for the assessment of tuberculosis treatment in the decision-making process regarding therapeutic interventions.

To determine the prevalence of diabetes mellitus among pulmonary tuberculosis patients and the difference of clinical characteristics and outcomes between pulmonary tuberculosis patients with and without diabetes mellitus in an aging population in Shanghai, China. This is a retrospective population-based study. 201 newly diagnosed pulmonary tuberculosis patients in Changning District, Shanghai during 2007-2008 were included. Clinical characteristics and outcomes were collected. Determination of diabetes mellitus was based on the medical records before pulmonary tuberculosis was diagnosed. The prevalence of diabetes mellitus among pulmonary tuberculosis patients was 19.9% (40/201). Pulmonary tuberculosis patients with diabetes mellitus were more likely to be old (≥50, OR=5.23, 95% CI=2.07-13.25), to have pulmonary cavities (OR=3.02, 95% CI=1.31-6.98), to be sputum smear positive (OR=2.90, 95% CI=1.12-7.51), and to have extension of anti-tuberculosis treatment duration (OR=2.68, 95% CI 1.17-6.14). Besides, they had a higher 2nd month sputum smear positive proportion (OR=2.97, 95% CI 1.22-7.22) and a higher 5-year recurrence rate (OR=5.87, 95% CI 1.26-27.40). High prevalence, severe clinical characteristics and poor outcomes of pulmonary tuberculosis patients with diabetes mellitus highlight the necessity of early bi-directional screening and co-management of these two diseases in Shanghai, China.

Objective: To assess the features and clinical significance of spiral dynamic CT in patients with pulmonary spheral tuberculosis. Methods: The 54 foci in 42 patients with pulmonary spheral tuberculosis were studied. Thin-sections at 2 mm thickness and 2 mm interval through the nodular center were obtained before and after administration of contrast material. Results: In 54 pulmonary spheral tuberculosis, maximum enhanced CT value in 51 (94.4%, 51/54) foci was less than 20 HU, and more than 20 HU in the other 3(5.6%, 3/54) foci. 27(50.0%, 27/54) foci showed no any enhancement, 24, (44%, 24/54) foci showed capsular enhancement, 1(1.9%, 1/54) focus showed peripheral enhancement and 2(3.7%, 2/54) foci showed extensive enhancement. The accuracy of the correct diagnosis was 25.9% in terms of plain CT and 94.4% in terms of enhanced CT scanning. The difference was significant (x 2 = 50.1, P < 0.05). The curative effect of extensive enhanced foci and peripheral enhanced foci was optimal, capsular enhanced foci was second, and non-enhanced foci was barely satisfactory. Conclusion: Spiral dynamic CT technique may improve the accuracy of diagnosing pulmonary spheral tuberculosis. No enhancement and/or capsular enhancement were suggestive of tuberculosis. The enhancing character of foci might contribute to assess the curative effect of anti-tuberculosis

Full Text Available Background. Tuberculosis (TB is a major cause of morbidity and mortality globally. Many cases are diagnosed on autopsy and a subset of patients may require surgical intervention either due to the complication or sequelae of TB. Materials and Methods. 40 cases of resected lung specimens following surgery or autopsy in which a diagnosis of pulmonary tuberculosis was made were included. Histopathological pattern analysis of pulmonary tuberculosis along with associated nonneoplastic changes and identification of Mycobacterium tuberculosis bacilli was done. Results. The mean age of diagnosis was 41 years with male predominance (92.5%. Tuberculosis was suspected in only 12.1% of cases before death. Seven cases were operated upon due to associated complications or suspicion of malignancy. Tubercular consolidation was the most frequent pattern followed by miliary tuberculosis. The presence of necrotizing granulomas was seen in 33 cases (82.5%. Acid fast bacilli were seen in 57.5% cases on Ziehl-Neelsen stain. Conclusion. Histopathology remains one of the most important methods for diagnosing tuberculosis, especially in TB prevalent areas. It should be considered in the differential diagnosis of all respiratory diseases because of its varied clinical presentations and manifestations.

Because small, pliable paediatric airways are easily compressed by enlarged lymph nodes, detection of radiographic airway compression might be an objective criterion for diagnosing pulmonary tuberculosis. To investigate the frequency and inter-observer agreement of airway compression on chest radiographs in children with pulmonary tuberculosis compared to those with a different lower respiratory tract infection. Chest radiographs of children with suspected pulmonary tuberculosis were read by two readers according to a standardised format and a third reader when there was disagreement. Radiographs of children with proven pulmonary tuberculosis were compared to those with a different lower respiratory tract infection. We evaluated frequency and location of radiographic airway compression. Findings were correlated with human immunodeficiency virus (HIV) status and age. We assessed inter-observer agreement using kappa statistics. We reviewed radiographs of 505 children (median age 25.9 months, interquartile range [IQR] 14.3-62.2). Radiographic airway compression occurred in 54/188 (28.7%) children with proven pulmonary tuberculosis and in 24/317 (7.6%) children with other types of lower respiratory tract infection (odds ratio [OR] 4.9; 95% confidence interval [CI] 2.9-8.3). A higher frequency of radiographic airway compression occurred in infants (22/101, or 21.8%) compared to older children (56/404, or 13.9%; OR 1.7; 95% CI 1.0-3.0). We found no association between airway compression and HIV infection. Inter-observer agreement ranged from none to fair (kappa of 0.0-0.4). There is a strong association between airway compression on chest radiographs and confirmed pulmonary tuberculosis. However this finding's clinical use as an objective criterion for diagnosis of pulmonary tuberculosis in children is limited by poor inter-observer agreement. (orig.)

Full Text Available Aim. To analyze the peculiarities and mechanisms of receptor-mediated T-lymphocytes disorders in different clinical forms of pulmonary tuberculosis.Materials and мethods. The study involved 116 patients with first diagnosed infiltrative and disseminated drug-sensitive and drug-resistant pulmonary tuberculosis. The key stages in receptor-mediated activation of T-lymphocytes, isolated from blood, after their CD3/CD28-induction in vitro with addition of intracellular transport blocker were analyzed. Their immunotyping was carried out with the method of two- and threecolor flow cytofluorometry. The obtained results were statistically analyzed.Results. The breach of extracellular and intracellular stages of T-lymphocytes activation, shown by reduction in total number of CD3- and CD28-positive cells, and CD3+CD28+IL2+, CD3+CD28+IL2–, CD3+NF-kB+, CD3+NFAT2+ lymphocytes, and increase in number of CD3+CTLA4+ cells, was identified with most of their manifestations in disseminated drug-resistant pulmonary tuberculosis. It was shown that the content of CD3+AP-1+ lymphocytes is variable in drug-resistant pulmonary tuberculosis: it increases in the infiltrative form and decreases in the disseminated form.Conclusion. The results showed different mechanisms leading to a deficiency of IL-2-positive lymphocytes and T-lymphocytopenia: from “functional reserve” exhaustion of T-cells in drug-sensitive pulmonary tuberculosis to immunosuppression under the influence of suppressive cytokines (in case of the infiltrative form and inhibitory protein CTLA4 (in case of the disseminated form in drug-resistant pulmonary tuberculosis. 

Loss of receptor on tuberculin-reactive T-cells marks active pulmonary tuberculosis.

Directory of Open Access Journals (Sweden)

Mathias Streitz

Full Text Available BACKGROUND: Tuberculin-specific T-cell responses have low diagnostic specificity in BCG vaccinated populations. While subunit-antigen (e.g. ESAT-6, CFP-10 based tests are useful for diagnosing latent tuberculosis infection, there is no reliable immunological test for active pulmonary tuberculosis. Notably, all existing immunological tuberculosis-tests are based on T-cell response size, whereas the diagnostic potential of T-cell response quality has never been explored. This includes surface marker expression and functionality of mycobacterial antigen specific T-cells. METHODOLOGY/PRINCIPAL FINDINGS: Flow-cytometry was used to examine over-night antigen-stimulated T-cells from tuberculosis patients and controls. Tuberculin and/or the relatively M. tuberculosis specific ESAT-6 protein were used as stimulants. A set of classic surface markers of T-cell naïve/memory differentiation was selected and IFN-gamma production was used to identify T-cells recognizing these antigens. The percentage of tuberculin-specific T-helper-cells lacking the surface receptor CD27, a state associated with advanced differentiation, varied considerably between individuals (from less than 5% to more than 95%. Healthy BCG vaccinated individuals had significantly fewer CD27-negative tuberculin-reactive CD4 T-cells than patients with smear and/or culture positive pulmonary tuberculosis, discriminating these groups with high sensitivity and specificity, whereas individuals with latent tuberculosis infection exhibited levels in between. CONCLUSIONS/SIGNIFICANCE: Smear and/or culture positive pulmonary tuberculosis can be diagnosed by a rapid and reliable immunological test based on the distribution of CD27 expression on peripheral blood tuberculin specific T-cells. This test works very well even in a BCG vaccinated population. It is simple and will be of great utility in situations where sputum specimens are difficult to obtain or sputum-smear is negative. It will also help

While it is still a common practice of some clinicians to rely on chest radiography examination alone for the diagnosis of pulmonary tuberculosis, others still claim that absolute diagnosis of tuberculosis can firmly be established by bacteriological examination from secretions or tissues of the infected host. This study will evaluate the relationship between radiographic findings (CXR) and the likelihood of finding tubercle bacilli on sputum acid-fast bacilli (AFB) culture in pulmonary tuberculosis at Lung Center of the Philippines. Of 41 individuals who submitted their sputum for AFB culture, tubercle bacilli in the sputum was shown in 25 (60%) of cases and no growth of tubercle bacilli in 16 (40%) of cases. Chest radiography reading revealed tuberculosis in 100% of cases, of which when classified further, 22 (54%) has fibrohazed or hazy infiltrates on their CXR, 7 (17%) has cavitations or interpreted as moderate or far advanced TB, 12 (29%) has fibroid, nodular infiltrates or densities. In patients radiologically diagnosed as PTB minimal, sputum culture revealed tubercle bacilli in 15 (57%) among moderate, far advanced tuberculosis, and 6 (50%) among those with inactive or old tuberculosis. Therefore, the probability of detecting tubercle bacilli in pulmonary tuberculosis is not greatly influenced by radiographic findings. (auth.). 11 refs.; 2 figs.; 2 tabs

Tuberculosis, more than any other infectious disease, has always been a challenge, since it has been responsible for a great amount of morbidity and mortality in humans. After a steady decline in the number of new cases during the twentieth century, due to improved social and environmental conditions, early diagnosis, and the development of antituberculous medication, a stagnation and even an increase in the number of new cases was noted in the mid-1980s. The epidemiological alteration is multifactorial: global increase in developing countries; minority groups (HIV and other immunocompromised patients); and elderly patients due to an altered immune status. Other factors that may be responsible are a delayed diagnosis, especially in elderly patients, incomplete or inadequate therapy, and the emergence of multidrug-resistant tuberculosis. The course of the disease and its corresponding clinicoradiological pattern depends on the interaction between the organism and the host response. Classically, pulmonary tuberculosis has been classified in primary tuberculosis, which occurred previously in children, and postprimary tuberculosis, occurring in adult patients. In industrialized countries, however, there seems to be a shift of primary tuberculosis towards adults. Furthermore, due to an altered immunological response in certain groups, such as immunocompromised and elderly patients, an atypical radioclinical pattern may occur. The changing landscape, in which tuberculosis occurs, as well as the global resurgence, and the changed spectrum of the clinical and radiological presentation, justify a renewed interest of radiologists for the imaging features of pulmonary tuberculosis. This article deals with the usual imaging features of pulmonary tuberculosis as well as the atypical patterns encountered in immunodepressed and elderly patients. (orig.)

Classification of pulmonary tuberculosis designated by the Japanese Society for Tuberculosis is a classification of pulmonary tuberculosis on radiographs findings. We analyzed both radiographs and CT in 150 patients with lung tuberculosis at the diagnosis based on the society classification. In 52 patients, the classification by radiographs was not consistent with that by CT. Generally, radiographs missed small and faint opacities in the lung. There were cases which showed tuberculous opacities in CT, diagnosed as normal by Radiographs. It is concluded that the diagnosis of the pulmonary tuberculosis by chest radiographs may lead to underdiagnosis and underestimation of its severity. Hence, chest CT is very useful for making an accurate diagnosis. (author)

Objective: To evaluate CT and X-ray features of pulmonary tuberculosis in diabetic patients, patients post kidney transplantation, and patients with acquired immunodeficiency syndrome (AIDS). Methods: The authors reviewed CT scans in 20 patients with diabetic patients, X-ray films in 10 cases after kidney transplantation, and CT scans in 2 patients with AIDS. Results: CT features of pulmonary tuberculosis in diabetic diseases included larger confluent consolidation (10 cases ), multiple small cavities within any given lesion (9 cases ) and non-segmental distribution (2 cases). Satellite lesions were found in most films. The X-ray appearances of pulmonary tuberculosis post kidney transplantation included patch and larger confluent consolidation (6 cases), and miliary tuberculosis(4 cases). The CT findings of pulmonary tuberculosis with AIDS were enlarged mediastinal lymph nodes (1 case), pulmonary infiltration (1 case), and extra chest lesions(2 cases) such as enlarged neck lymph nodes and post-peritoneal lymph nodes. Conclusion: The Main radiological findings of pulmonary tuberculosis in immunocompromised patients appear larger confluent consolidation, multiple small cavities within a given lesion, miliary tuberculosis, enlarged mediastinal lymph nodes, and extra chest enlarged lymph nodes

Objective: To investigate CT features of similar Hexheimer's reaction during initial treatment of active pulmonary tuberculosis. Methods: The similar Hexheimer's reaction in 44 patients diagnosed by clinic and follow-up CT scans were retrospectively reviewed by three radiologists. Results: During initial treatment of active pulmonary tuberculosis, development of radiographic progression were observed in 57 foci, including 28 pulmonary lesions increased at the site of their original lesion or new opacities elsewhere, ipsilateral or contralateral to the original lesion or both, 10 lesions related to the pleura (pleural effusion, pleural tuberculoma), 15 lymphadenectasis, 3 thymus reactions, and 1 cardiac pericardium thickening, respectively. These reactions appeared from the 20 days to 3.5 months, then with continuation of the initial chemotherapy for 1.0-3.0 months, the radiographic response was excellent with the areas of progression and the original lesions demonstrating resolution or improvement. Conclusion: The CT appearances of similar Hexheimer's reaction during initial treatment of active tuberculosis are specific to a certainty. (authors)

Full Text Available Introduction: The tuberculosis continues being a world problem and in the last years had an increase in his incidence mainly by the growing number of patients with HIV. The tuberculosis has like an etiologic agent the Mycobacterium tuberculosis that possesses a period of latency generally prolonged between the initial infection and the illness. That illness can affect diverse organs and systems. M Method: This study is descriptive, transversal and prospective. Within, patients diagnosed with pulmonary tuberculosis by the service of pneumologia of the outpatient clinic Araújo Lima of the Federal University of the Amazon (UFAM, in Manaus, between the period of July of 2005 and May of 2006 were submitted to otorhinolaryngological exam in search of manifestations of the illness. Objectives: The main objective of the study was estimate the predominance of otorhinolaryngological manifestations in patients with tuberculosis and to describe the frequencies of the different manifestations. Results: They were analyzed 15 cases of pulmonary tuberculosis confirmed by the baciloscopia, being 7 of the female sex and 8 of the male sex. The majority of the patients were young adults between the third and fourth decade of life (46,7%. Only one of the patients had co-infection with the HIV virus. Conclusion: The otorhinolaryngological affection by the tuberculosis was observed in 2 patients corresponding to 13.33% of the sample, being a patient with tubercular medium otitis and a patient with linfoadenopatia cervical.

Introduction: It was usually assumed that pulmonary tuberculosis (TB) in HIV-seropositive patients represents reactivation TB, despite the radiographic appearance frequently consistent rather with a recent disease. Hence, these radiographic features were considered 'atypical'. We have hypothesised that the so called 'atypical' radiographic features could be due to a greater proportion of primary TB among these patients, representing the typical appearance of primary radiological pattern. Material and methods: We reviewed chest imaging of 219 HIV+ patients with microbiological proven pulmonary tuberculosis, who were assessed for the presence, number, distribution of cavitations and for associated pulmonary parenchymal abnormalities, adenopathies and pleural effusion, and were classified as a primary or post-primary pattern. Results: The patients with post-primary pattern were 50%, and the rate of cavitation was 63%, not wandering off the general population. Cavities still occurred with similar proportion in groups with CD4 200 cells/mm 3 . Conclusion: We suggest that HIV-related pulmonary tuberculosis is typical in its radiological appearances, consistent with those of the general population, and this could be confirmed by the most recent molecular epidemiological techniques that allow to definitely classify the tuberculosis episodes as either primary or post-primary disease

Background An increasing number of studies have implicated the microbiome in certain diseases, especially chronic diseases. In this study, the bacterial communities in the sputum of pulmonary tuberculosis patients were explored. Total DNA was extracted from sputum samples from 31 pulmonary tuberculosis patients and respiratory secretions of 24 healthy participants. The 16S rRNA V3 hyper-variable regions were amplified using bar-coded primers and pyro-sequenced using Roche 454 FLX. Results The results showed that the microbiota in the sputum of pulmonary tuberculosis patients were more diverse than those of healthy participants (ppulmonary tuberculosis patients and 17 of which were found in healthy participants. Furthermore, many foreign bacteria, such as Stenotrophomonas, Cupriavidus, Pseudomonas, Thermus, Sphingomonas, Methylobacterium, Diaphorobacter, Comamonas, and Mobilicoccus, were unique to pulmonary tuberculosis patients. Conclusions This study concluded that the microbial composition of the respiratory tract of pulmonary tuberculosis patients is more complicated than that of healthy participants, and many foreign bacteria were found in the sputum of pulmonary tuberculosis patients. The roles of these foreign bacteria in the onset or development of pulmonary tuberculosis shoud be considered by clinicians. PMID:23176186

New approaches to define factors underlying the immunopathogenesis of pulmonary diseases including sarcoidosis and tuberculosis are needed to develop new treatments and biomarkers. Comparing the blood transcriptional response of tuberculosis to other similar pulmonary diseases will advance knowledge of disease pathways and help distinguish diseases with similar clinical presentations. To determine the factors underlying the immunopathogenesis of the granulomatous diseases, sarcoidosis and tuberculosis, by comparing the blood transcriptional responses in these and other pulmonary diseases. We compared whole blood genome-wide transcriptional profiles in pulmonary sarcoidosis, pulmonary tuberculosis, to community acquired pneumonia and primary lung cancer and healthy controls, before and after treatment, and in purified leucocyte populations. An Interferon-inducible neutrophil-driven blood transcriptional signature was present in both sarcoidosis and tuberculosis, with a higher abundance and expression in tuberculosis. Heterogeneity of the sarcoidosis signature correlated significantly with disease activity. Transcriptional profiles in pneumonia and lung cancer revealed an over-abundance of inflammatory transcripts. After successful treatment the transcriptional activity in tuberculosis and pneumonia patients was significantly reduced. However the glucocorticoid-responsive sarcoidosis patients showed a significant increase in transcriptional activity. 144-blood transcripts were able to distinguish tuberculosis from other lung diseases and controls. Tuberculosis and sarcoidosis revealed similar blood transcriptional profiles, dominated by interferon-inducible transcripts, while pneumonia and lung cancer showed distinct signatures, dominated by inflammatory genes. There were also significant differences between tuberculosis and sarcoidosis in the degree of their transcriptional activity, the heterogeneity of their profiles and their transcriptional response to treatment.

X-ray picture has been analysed in patients of 2 groups. The 1st group included 120 patients with disseminated tuberculosis, the 2 nd one 56 patients with systemic diseases (lupus erythematosus and scleroderma). The disease initial diagnosis was erroneous in 8 cases (4.5%), i.e. in 5 patients tuberculosis was unrecognized, and in 3 the systemic disease. It is marked, that x-ray pulmonary alterations bore interstitial character in collagenoses, and focal in tuberculosis. Predominant apical posterior lung segment lesion was detected in 95% of cases in tuberculosis, while caverns were diagnosed in 65.8%. Besides, radiographic features of the gastrointestinal tract, the skeleton, and the heart damage were established in 82.9% of systemic scleroderma patients.

Interferon-gamma (IFN-γ) release assays (IGRAs) are used to diagnose tuberculosis (TB) but not to measure treatment response. To measure IFN-γ response to active anti-tuberculosis treatment. Patients from the Henan Provincial Chest Hospital, Henan, China, with TB symptoms and/or signs were enrolled into this prospective, observational cohort study and followed for 6 months of treatment, with blood and sputum samples collected at 0, 2, 4, 6, 8, 16 and 24 weeks. The QuantiFERON® TB-Gold assay was run on collected blood samples. Participants received a follow-up telephone call at 24 months to determine relapse status. Of the 152 TB patients enrolled, 135 were eligible for this analysis: 118 pulmonary (PTB) and 17 extra-pulmonary TB (EPTB) patients. IFN-γ levels declined significantly over time among all patients (P = 0.002), with this decline driven by PTB patients (P = 0.001), largely during the initial 8 weeks of treatment (P = 0.019). IFN-γ levels did not change among EPTB patients over time or against baseline culture or drug resistance status. After 6 months of effective anti-tuberculosis treatment, IFN-γ levels decreased significantly in PTB patients, largely over the initial 8 weeks of treatment. IFN-γ concentrations may offer some value for monitoring anti-tuberculosis treatment response among PTB patients.

Full Text Available A family is a social group that satisfies the most important needs and fulfils diverse functions. Patients with infiltrative pulmonary tuberculosis are not emotionally supported by their family members and hence experience anger and exasperation. The functioning of 30 families of patients with infiltrative pulmonary tuberculosis was psychologically studied using the family environment scale. The findings were compared with those of 100 standard families. Six out of 10 items showed significant differences, the other 4 items also displayed dissimilarities, but the latter were insignificant. The families of patients with pulmonary tuberculosis were dysfunctional. The social climate of the family had established well before infiltrative tuberculosis was diagnosed in its member. The dissimilarities from the standard families are due to the social characteristics of family members, such as low income, alcohol abuse, and imprisonment. The specific features of the social climate of a family provide an explanation for no moral support to the patient.

Pulmonary tuberculosis caused by Mycobacterium tuberculosis remains a global problem. Inflammatory responses are the primary characteristics of patients with pulmonary tuberculosis in intensive care units (ICU). The aim of the present study was to investigate the clinical importance of inflammatory cells and factors for patients with pulmonary tuberculosis in ICU. A total of 124 patients with pulmonary tuberculosis in ICU were recruited for the present study. The inflammatory responses in patients with pulmonary tuberculosis in ICU were examined by changes in inflammatory cells and factors in the serum. The results indicated that serum levels of lymphocytes, plasma cells, granulocytes and monocytes were increased in patients with pulmonary tuberculosis in ICU compared with healthy controls. The serum levels of inflammatory factors interleukin (IL)-1, IL-6, IL-10, IL-12, and IL-4 were upregulated in patients with pulmonary tuberculosis in ICU. Lower plasma concentrations of IL-2, IL-15 and interferon-γ were detected in patients with pulmonary tuberculosis compared with healthy controls. It was demonstrated that high mobility group box-1 protein expression levels were higher in the serum of patients with pulmonary tuberculosis compared with healthy controls. Notably, an imbalance of T-helper cell (Th)1/Th2 cytokines was observed in patients with pulmonary tuberculosis. Pulmonary tuberculosis caused by M. tuberculosis also upregulated expression of matrix metalloproteinase (MMP)-1 and MMP-9 in hPMCs. In conclusion, these outcomes demonstrated that inflammatory responses and inflammatory factors are associated with the progression of pulmonary tuberculosis, suggesting that inhibition of inflammatory responses and inflammatory factors may be beneficial for the treatment of patients with pulmonary tuberculosis in ICU.

Chromoblastomycosis is caused by dematiaceous fungi. It develops after inoculation of the organism into the skin. We report a case of chromoblastomycosis in a pulmonary tuberculosis patient without known history of trauma. The lesions were initially diagnosed as sporotrichosis and skin tuberculosis. Histopathology of scales and skin biopsy specimen revealed sclerotic bodies, the hallmark of chromoblastomycosis. The causative organism was identified as Fonsecaea monophora by rDNA ITS sequencing. The lesions recovered markedly after two month treatment with oral terbinafine 250 mg daily according to drug sensitive test in vitro in combination with local thermotherapy.

Tc-99m ciprofloxacin is available for imaging infection. However, there has been no study on employing single photon emission computed tomography (SPECT) with using Tc-99m ciprofloxacin to image active pulmonary tuberculosis. Therefore, we conducted this study to assess the efficacy of Tc-99m ciprofloxacin SPECT for imaging active pulmonary tuberculosis. Twenty-one participants were enrolled in this prospective study. They were divided into two groups according to the clinical and radiological assessment. Group one (Gr. 1) consisted of five normal volunteers and six patients with inactive pulmonary tuberculosis. Group two (Gr. 2) consisted of ten patients with active pulmonary tuberculosis. SPECT was performed 3 h after injecting 555 MBq (15 mCi) of Tc-99m ciprofloxacin. The findings of Tc-99m ciprofloxacin SPECT were interpreted by a nuclear medicine specialist and then the results were analyzed according to the patients' clinical and radiological classifications. The results of Tc-99m ciprofloxacin SPECT were as follows: eight true-positive cases, ten true-negative cases, one false-positive case and two false-negative cases. The sensitivity and specificity was 80.0% and 90.0%, respectively. The positive predictive value was 88.9% and the negative predictive value was 83.3%. Conclusions Tc-99m ciprofloxacin SPECT is feasible for imaging active pulmonary tuberculosis. It is a useful nuclear-imaging method for discriminating between the active and inactive tuberculosis states in patients with a past medical history of pulmonary tuberculosis.

Diagnosis of tuberculosis (TB) is not always easy, thus employing methods with a short duration and acceptable sensitivity and specificity is necessary to diagnose TB. The aim of this study was to investigate the diagnostic value of serum adenosine deaminase (ADA) level for diagnosis of pulmonary tuberculosis. A total of 160 sex and age-matched subjects were included in this study, and were divided to four groups; forty patients with pulmonary tuberculosis (PTB) diagnosed based on the national TB program (NTP), forty patients with non-tuberculosis bacterial pneumonia, forty patients with lung cancer and forty people who were healthy in every respect. Serum adenosine deaminase activity in patients of each group was measured by the Giusti and Galanti calorimetry method using a commercial kit (Diazyme, USA). The ANOVA analysis was used to compare groups for quantitative variables. Mean serum ADA level in the PTB group was clearly higher than the mean serum ADA in the other three groups. Mean serum ADA was 26 IU/L in PTB patients, 19.48 IU/L in patients with pneumonia, 15.8 IU/L in patients with lung cancer, and 10.7 IU/L in the control group (P ADA in patients with PTB sensitivity and specificity was defined as 35% and 91%, respectively. Serum ADA activity with high specificity percentage may be a useful alternative test in restricted resource areas to rule out diagnosis of PTB. However, serum ADA activity is not a useful tool for TB diagnosis.

The objective of this systematic review was to select articles including chest X-ray or chest CT findings in patients who developed pulmonary tuberculosis following solid organ transplantation (lung, kidney, or liver). The following search terms were used: "tuberculosis"; "transplants"; "transplantation"; "mycobacterium"; and "lung". The databases used in this review were PubMed and the Brazilian Biblioteca Virtual em Saúde (Virtual Health Library). We selected articles in English, Portuguese, or Spanish, regardless of the year of publication, that met the selection criteria in their title, abstract, or body of text. Articles with no data on chest CT or chest X-ray findings were excluded, as were those not related to solid organ transplantation or pulmonary tuberculosis. We selected 29 articles involving a collective total of 219 patients. The largest samples were in studies conducted in Brazil and South Korea (78 and 35 patients, respectively). The imaging findings were subdivided into five common patterns. The imaging findings varied depending on the transplanted organ in these patients. In liver and lung transplant recipients, the most common pattern was the classic one for pulmonary tuberculosis (cavitation and "tree-in-bud" nodules), which is similar to the findings for pulmonary tuberculosis in the general population. The proportion of cases showing a miliary pattern and lymph node enlargement, which is most similar to the pattern seen in patients coinfected with tuberculosis and HIV, was highest among the kidney transplant recipients. Further studies evaluating clinical data, such as immunosuppression regimens, are needed in order to improve understanding of the distribution of these imaging patterns in this population.

Radioiodine may accumulate at sites of inflammation or infection. We have seen such accumulation in six thyroid cancer patients with a history of previously treated pulmonary tuberculosis. We also review the causes of false-positive radioiodine uptake in lung infection/inflammation. Eight foci of radioiodine uptake were seen on six iodine-123 diagnostic scans. In three foci, the uptake was focal and indistinguishable from thyroid cancer pulmonary metastases from thyroid cancer. In the remaining foci, the uptake appeared nonsegmental, linear or lobar, suggesting a false-positive finding. The uptake was unchanged, variable in appearance or non-persistent on follow-up scans and less extensive than the fibrocystic changes seen on chest radiographs. In the two patients studied, thyroid hormone level did not affect the radioiodine lung uptake and there was congruent gallium-67 uptake. None of the patients had any evidence of thyroid cancer recurrence or of reactivation of tuberculosis and only two patients had chronic intermittent chest symptoms. Severe bronchiectasis, active tuberculosis, acute bronchitis, respiratory bronchiolitis, rheumatoid arthritis-associated lung disease and fungal infection such as Allescheria boydii and aspergillosis can lead to different patterns of radioiodine chest uptake mimicking pulmonary metastases. Pulmonary scarring secondary to tuberculosis may predispose to localized radioiodine accumulation even in the absence of clinically evident active infection. False-positive radioiodine uptake due to pulmonary infection/inflammation should be considered in thyroid cancer patients prior to the diagnosis of pulmonary metastases. (orig.)

The founder of humanistic psychology A. Maslow divided the needs of a personality into several levels--from the lowest to the highest ones. Higher-leveled needs rise when the lower-leveled needs are satisfied. A great deal of factors affect the origination and satisfaction of needs, but they are always interrelated with social values. The extent to which personality needs are satisfied in patients with pulmonary tuberculosis has not been studied. A special questionnaire has been drawn up to study the extent to which personality needs are met. Its suitability has been determined, by using a group of patients with bronchial asthma. The extent to which personality needs are satisfied in patients with pulmonary tuberculosis was studied in 178 patients with infiltrative pulmonary tuberculosis and 253 patients with fibrocavernous pulmonary tuberculosis. The results have shown that the extent to which personality needs are satisfied in patients with tuberculosis is lower than that in apparently healthy individuals of the same social status. In females with infiltrative pulmonary tuberculosis, the needs for safety are satisfied to a lesser extent. In those with fibrocavernous pulmonary tuberculosis, the extent to which the physiological, safety, and self-realization needs is decreased. In males with infiltrative pulmonary tuberculosis, the physiological, noetic, and self-realization needs are satisfied to a lesser extent. In those with fibrocavernous pulmonary tuberculosis, the extent to which the physiological, safety, group decision-making, noetic and self-realization needs is decreased.

Full Text Available Background: A lot of stigma and misconceptions about pulmonary tuberculosis still persist, in spite of the advances in treatment. Thus, a mere diagnosis of pulmonary tuberculosis can be a psychological trauma to an individual. The situation has aggravated with the association of tuberculosis with HIV infection. Aim: To study the psychiatric morbidity due to the various psychological stresses faced by a patient of pulmonary tuberculosis. Materials and Methods: The study group consisted of 100 inpatients admitted to pulmonary ward with diagnosis of pulmonary tuberculosis. The control group consisted of 100 inpatients admitted to pulmonary ward with nontuberculous pulmonary diseases. Psychiatric history and mental status were recorded on a specially designed proforma and diagnosis of any psychiatric illness, if present, arrived at as per International Classification of Diseases (ICD-10. The psychiatric tests applied were beck's depression inventory (BDI and Taylor's Manifest Anxiety Scale (TMAS. Results: Of the patients of pulmonary tuberculosis, 24% could be given a diagnostic category, as per ICD-10, as compared to only 8% of the controls (P < 0.005. On BDI, 44% of patients of pulmonary tuberculosis showed depression as compared to 27% of the controls (P < 0.02. On TMAS, 38% of patients of pulmonary tuberculosis showed anxiety as compared to 24% of controls (P < 0.05. A greater incidence of depression (on BDI and anxiety (on TMAS was seen in those with longer duration of illness (P < 0.02 and in those with greater severity of illness (P < 0.02. Conclusion: In view of the high psychiatric morbidity associated with pulmonary tuberculosis, there is enough scope for psychiatric services to be made available to these patients. In addition, personnel involved in the treatment of these patients should be trained for early detection of psychiatric symptoms.

Usual chest radiographic findings in pulmonary tuberculosis are well described in radiologic literatures for both primary and postprimary phases of disease. During the last decade, many authors have enumerated the unusual manifestations of pulmonary tuberculosis in adult population. These unusual findings usually have been involved in the frequent failure of both radiologist and clinician to recognize that tuberculosis could be the cause of a abnormal chest radiograph in patients who are finally and surprisingly proven to have tuberculosis. Authors have evaluated 249 patients who were admitted and newly proven to have adult-onset pulmonary tuberculosis at Chung-Ang University Hospital from January, 1985 to December, 1986. Unusual findings were noted in 76 (30.5%) of the 249 patients with adult-onset pulmonary tuberculosis. These unusual findings most frequently could be seen in 3rd decades and showed no sex difference in incidence. A broad spectrum of abnormal findings including usual and unusual abnormalities were procedure by adult-onset pulmonary tuberculosis. The unusual radiographic findings were arbitrarily classified. Pleural effusion without parenchymal disease (10.0%), unusual location of infiltrate (5.6%) and atelectasis (3.2%) were relatively common. Hilar and / or mediastinal lymphnode enlargement (1.6%), cavity without parenchymal infiltrates (1.6%), septic lung-like infiltrates (1.6%), completely clear lungs (1.2%), miliary infiltrates (1.2%), fibrocalcific scar-like infiltrates (1.2%), masslike density (1.2%) and rheumatoid lung-like infiltrates (1.2%) were occasionally noted. Pneumothorax without parenchymal disease (0.4%) and bron chocutaneous fistula (0.4%) are. The recognition of these unusual findings could further improve the detection and diagnosis of adult-onset pulmonary tuberculosis

Objective: To analyze image characteristics of pulmonary tuberculosis associated with diabetes mellitus and observe the changes of pulmonary tuberculotic lesions influenced by the state of hyperglycosemia. Methods: Examinations of chest plain film and tomography were taken in 68 patients with pulmonary tuberculosis and diabetes, and additional CT scans were done in 38 patients among them. Radiological examinations of lung and blood sugar test were taken at the interval of 2, 3, and 4-6 months in all 68 patients under the treatment of regular blood sugar control and antituberculosis, which compared with 30 patients with pulmonary tuberculosis only. Results: The images of X-ray and CT showed major lesions of massive patchy shadow in 55 patients (80.9%), or multiple small patchy shadow in 13(19.1%) and cavity 61(89.7%). After 2 month's treatment, enlargement of patchy shadow and cavity were found in 9(23.7%)and 10(28.6%)cases, respectively with overall deterioration rates of 65.8% in group of 38 patients with level of blood sugar over 7.0 mmol/L, which was significantly higher than that of the control group 7.0 mmol/L(x 2 =16.4, P 2 = 0.81, P>0.5) with the well controlled blood sugar after treatment of 3 months or more. The follow-up images showed similar results between the groups of pulmonary tuberculosis only and the group of pulmonary tuberculosis with high level of blood sugar, in which the overall deterioration rates was significant less than the group of pulmonary tuberculosis with level of blood sugar more than 8.0 mmol/L(x 2 =5.46, P<0.025). Conclusion: There are imaging characteristics in patient with pulmonary tuberculosis and diabetes mellitus. The state of hyperglycosemia is a vital factor, which influences the radiological changes of pulmonary tuberculosis

When bronchogenic carcinoma is coexisting with pulmonary tuberculosis, it is difficult to differentiate bronchogenic carcinoma from pulmonary tuberculosis radiographically. Thus, the object of this study is to define differential diagnosis of bronchogenic carcinoma by computed tomography. We analyzed CT scans of 27 patients with radiologic findings of pulmonary tuberculosis and mass of which twelve cases were pulmonary tuberculosis and fifteen cases were primary lung cancer. The location of parenchymal infiltration and the mass was the same in 60%(9/15) of the primary lung cancer in cases and 83%(10/12) of the pulmonary tuberculosis cases. The common location of the mass was the both upper lobes in 92%(11/12) of the pulmonary tuberculosis cases and 53%(8/15) of the primary lung cancer cases. The common locations of the mediastinal lymphadenopathy were 4R, 2R of the pulmonary tuberculosis cases and 4R, 10R of the primary lung cancer cases. In the feature of post enhanced lymph nodes, homogenous increased density was more frequent in primary lung cancer. Measurements of the maximum thickness part of the cavity wall was not a reliable indication of malignancy

In 20 normal cases and 39 pulmonary tuberculosis cases, regional pulmonary arterial blood flow measurement and lung perfusion scans by 131 I-Macroaggregated albumin, lung inhalation scans by colloidal 198 Au and spirometries by respirometer were done at the Radiological Research Institute. The measured lung function tests were compared and the results were as the following: 1) The normal distribution of pulmonary blood flow was found to be 54.5±2.82% to the right lung and 45.5±2.39% to the left lung. The difference between the right and left pulmonary arterial blood flow was significant statistically (p 131 I-MAA in patients with pulmonary tuberculosis was as follows: a) In the pretreated minimal pulmonary tuberculosis, the decreased area of pulmonary arterial blood flow was corresponding to the chest roentgenogram, but the decrease of pulmonary arterial blood flow was more extensive than had been expected from the chest roentgenogram in the apparently healed minimal pulmonary tuberculosis. b) In the pretreated moderately advanced pulmonary tuberculosis, the decrease of pulmonary arterial blood flow to the diseased area was corresponding to the chest roentgenogram, but the decrease of pulmonary arterial blood flow was more extensive in the treated moderately advanced pulmonary tuberculosis as in the treated minimal pulmonary tuberculosis. c) Pulmonary arterial blood flow in the patients with far advanced pulmonary tuberculosis both before and after chemotherapy were almost similar to the chest roentgenogram. Especially the decrease of pulmonary arterial blood flow to the cavity was usually greater than had been expected from the chest roentgenogram. 3) Lung inhalation scan by colloidal 198 Au in patients with pulmonary tuberculosis was as follows: a) In the minimal pulmonary tuberculosis, lung inhalation scan showed almost similar decrease of radioactivity corresponding to the chest roentgenogram. b) In the moderately advanced pulmonary tuberculosis the decrease

We performed ventilation-perfusion scintigraphy in 13 patients with pulmonary tuberculosis sequelae and 21 with chronic obstructive pulmonary disease. We used 99m Tc-MAA for perfusion scintigram and 133 Xe gas for ventilation scintigram. We added the radioactivities during the rebreathing phase of the ventilation scintigram to make a computerized image of the lung volume. Regions of interest (ROIs) were derived from radioactivities on each image. ROIs included each whole lung on lung volume (L) image and areas where radioactivity was greater than 70% of the highest radioactivity on perfusion (P70) image. We counted the area of ROIs on L and P70, and used the ratio of perfusion to lung volume (P70/L) as a parameter of pulmonary perfusion. P70/L in patients with pulmonary tuberculosis sequelae was significantly higher than that in those with COPD. This suggested that the area of high pulmonary perfusion is larger in the patients with pulmonary tuberculosis sequelae as compared with those with COPD. (author)

T-SPOT.TB test was performed according to the kit instruction operation. 2.5×105 peripheral blood mononuclear cells (PBMCs were added into the pre- coated anti- human γ- interferon antibody, and co-incubated separately with two specific My. tuberculosis antigens, namely early secretory targeting 6 (ESAT-6 and culture filtration protein 10 (CFP-10, and then the spot forming cells (SFCs were counted. The gold standard for present study were set as follows: 1 My. tuberculosis smear positive or culture positive; 2 Clinical diagnosis (meet any one is positive. The efficacy of T-SPOT.TB on diagnosing active TB was observed, and then the optimal critical value for diagnosing active TB was determined. Patients diagnosed as active TB were divided into 4 subgroups: initial treatment group, retreatment group, smear or culture positive group, and smear or culture negative group. T-SPOT.TB was carried out to detect A and B antigen, and the difference of formed SFCs was then compared. The present study was approved by the Ethics Committee of Xinjiang Uygur Autonomous Region Chest Hospital. Results Of 700 cases suspected of pulmonary tuberculosis enrolled in present study, 528 out of 624 definite cases (84.6% were finally diagnosed as active tuberculosis (active TB group and 96 cases (15.4% were as without TB infection (non-TB group.

Idiopathic pulmonary fibrosis (IPF), also known as cryptogenic fibrosing alveolitis, is one of a spectrum of idiopathic interstitial pneumonia. IPF is an increasingly common condition which poses many diagnostic and therapeutic challenges leading to misdiagnosis and mismanagement. We presented a 55-year-old male textile trader who was initially managed as sputum-negative pulmonary tuberculosis before histology report. He presented to our clinic with Breathlessness and cough of 3 years and 2.5 years, respectively. He had commenced anti-tuberculosis two months before presentation without significant relief. General Physical examination and vital signs were essentially normal. SPO2 was 96% on room air. Chest Examination revealed end-inspiratory bi-basal velcro-like crackles. Other systemic examinations were normal. Radiological examination by way of chest X- ray and chest CT showed features suggestive of IPF. The patient also had open Lung biopsy for histology and spirometry which demonstrated restrictive ventilatory function pattern. A diagnosis of Interstitial lung disease probably Idiopathic Pulmonary Fibrosis was entertained. He was commenced on Tab prednisolone, Tab Rabeprazole, with minimal improvement. IPF have often been misdiagnosed and treated as pulmonary tuberculosis with unfavorable outcome.

Full Text Available Background and Objectives: Little evidence is available about the relationship between statins use and pulmonary tuberculosis in Taiwan. The aim of the study was to explore this issue.Methods: Using the database of the Taiwan National Health Insurance Program, we conducted a population-based case-control study to identify 8,236 subjects aged 20 years and older with newly diagnosed pulmonary tuberculosis from 2000 to 2013 as the cases. We randomly selected 8,236 sex-matched and age-matched subjects without pulmonary tuberculosis as the controls. Subjects who had at least one prescription of statins before the index date were defined as “ever use.” Subjects who never had one prescription of statins before the index date were defined as “never use.” The odds ratio (OR and 95% confidence interval (CI for pulmonary tuberculosis associated with statins use was estimated by a multivariable logistic regression model.Results: After adjustment for co-variables, the adjusted OR of pulmonary tuberculosis was 0.67 for subjects with ever use of statins (95% CI 0.59, 0.75. In a sub-analysis, the adjusted ORs of pulmonary tuberculosis were 0.87 (95% CI 0.69, 1.10 for subjects with cumulative duration of statins use <3 months, 0.77 (95% CI 0.58, 1.03 for 3–6 months, and 0.59 (95% CI 0.51, 0.68 for ≥6 months, compared with subjects with never use of statins.Conclusions: Statins use correlates with a small but statistically significant risk reduction of pulmonary tuberculosis. The protective effect is stronger for longer duration of statins use. Due to a case-control design, a causal-relationship cannot be established in our study. A prospective cohort design is needed to confirm our findings.

Full Text Available Abstract Background The diagnosis of pulmonary tuberculosis in patients with Human Immunodeficiency Virus (HIV is complicated by the increased presence of sputum smear negative tuberculosis. Diagnosis of smear negative pulmonary tuberculosis is made by an algorithm recommended by the National Tuberculosis and Leprosy Programme that uses symptoms, signs and laboratory results. The objective of this study is to determine the sensitivity and specificity of the tuberculosis treatment algorithm used for the diagnosis of sputum smear negative pulmonary tuberculosis. Methods A cross-section study with prospective enrollment of patients was conducted in Dar-es-Salaam Tanzania. For patients with sputum smear negative, sputum was sent for culture. All consenting recruited patients were counseled and tested for HIV. Patients were evaluated using the National Tuberculosis and Leprosy Programme guidelines and those fulfilling the criteria of having active pulmonary tuberculosis were started on anti tuberculosis therapy. Remaining patients were provided appropriate therapy. A chest X-ray, mantoux test, and Full Blood Picture were done for each patient. The sensitivity and specificity of the recommended algorithm was calculated. Predictors of sputum culture positive were determined using multivariate analysis. Results During the study, 467 subjects were enrolled. Of those, 318 (68.1% were HIV positive, 127 (27.2% had sputum culture positive for Mycobacteria Tuberculosis, of whom 66 (51.9% were correctly treated with anti-Tuberculosis drugs and 61 (48.1% were missed and did not get anti-Tuberculosis drugs. Of the 286 subjects with sputum culture negative, 107 (37.4% were incorrectly treated with anti-Tuberculosis drugs. The diagnostic algorithm for smear negative pulmonary tuberculosis had a sensitivity and specificity of 38.1% and 74.5% respectively. The presence of a dry cough, a high respiratory rate, a low eosinophil count, a mixed type of anaemia and

The Transcriptional Signature of Active Tuberculosis Reflects Symptom Status in Extra-Pulmonary and Pulmonary Tuberculosis.

Full Text Available Mycobacterium tuberculosis infection is a leading cause of infectious death worldwide. Gene-expression microarray studies profiling the blood transcriptional response of tuberculosis (TB patients have been undertaken in order to better understand the host immune response as well as to identify potential biomarkers of disease. To date most of these studies have focused on pulmonary TB patients with gene-expression profiles of extra-pulmonary TB patients yet to be compared to those of patients with pulmonary TB or sarcoidosis.A novel cohort of patients with extra-pulmonary TB and sarcoidosis was recruited and the transcriptional response of these patients compared to those with pulmonary TB using a variety of transcriptomic approaches including testing a previously defined 380 gene meta-signature of active TB.The 380 meta-signature broadly differentiated active TB from healthy controls in this new dataset consisting of pulmonary and extra-pulmonary TB. The top 15 genes from this meta-signature had a lower sensitivity for differentiating extra-pulmonary TB from healthy controls as compared to pulmonary TB. We found the blood transcriptional responses in pulmonary and extra-pulmonary TB to be heterogeneous and to reflect the extent of symptoms of disease.The transcriptional signature in extra-pulmonary TB demonstrated heterogeneity of gene expression reflective of symptom status, while the signature of pulmonary TB was distinct, based on a higher proportion of symptomatic individuals. These findings are of importance for the rational design and implementation of mRNA based TB diagnostics.

Tuberculosis is a public health problem in Mexico. From 1999 to 2002, we assessed retrospectively the epidemiological, clinical, and treatment characteristics of pulmonary tuberculosis in the hospitals of the Mexican Institute of Public Health in the state of Colima (Mexico). We included 184 cases diagnosed with pulmonary tuberculosis. A database containing demographic, epidemiological, and clinical information was constructed and analyzed. We estimate a median patient delay of 83 d and a mean treatment delay of 2.3 d. Of 14 cases suspected for multiresistance and microbiologically assayed, 5 were found to carry a multi-drug-resistant strain. We also found a significant association between a short patient delay and the presence of hemoptysis (p = 0.002) or dyspnea (p<0.001). 86 patients (46.8%) were sputum smear microscopy negative at the end of treatment and 40 (21.7%) completed treatment giving an overall success rate of 68.5%, which compares unfavorably with the World Health Organization target success rate of 85%. Five (2.7%) patients failed treatment, 10 (5.4%) died, 39 (21.2%) interrupted treatment, and 4 (2.2%) transferred to another reporting unit. A 2002 strategic change in drug distribution seemed to prove successful.

In tuberculosis endemic areas, patients with sputum positive for acid-fast bacilli (AFB) are usually diagnosed and treated for pulmonary tuberculosis. The diagnosis of nontuberculous mycobacteria (NTM) lung disease is often ascertained only after lung disease progression occurs, increasing the risk of severe morbidity and mortality. We conducted a matched case-control study among a prospective cohort of 300 patients with newly diagnosed AFB-positive sputum in Thailand during 2010-2012. We compared clinical and laboratory parameters and outcomes among patients with pulmonary tuberculosis, NTM lung disease and NTM colonization. A mycobacterial culture was performed in all patients. Ten patients with NTM lung disease were compared to 50 patients with pulmonary tuberculosis and 10 patients with NTM colonization. The presence of diabetes mellitus or human immunodeficiency virus infection, were associated with NTM lung disease (p = 0.030). Patients with NTM lung disease had a significantly lower body weight prior to treatment (p = 0.021), a higher body weight change from baseline (p = 0.038), and were more likely to have cavitations on chest radiograph (p = 0.033) than those with NTM colonization. In tuberculosis endemic areas, mycobacterial identification should be performed among patients with impaired immune function. NTM lung disease treatment should be considered in patients with NTM sputum isolates who have a history of significant weight loss or cavitations on chest radiography.

Altogether 203 patients (186 with destructive pulmonary tuberculosis, 11 with other forms of tuberculosis of respiratory tract organs, 6 with lung malignant tumor) were examined with the use of different modifications of tomography: longitudinal and oblique blurring, zonography, selective tomography. Standardization in the use of different methods is proposed, depending on the intensity of the main syndromes of pulmonary tissue lesions: limited shading, foci, dissemination, caverns, etc. The informativeness is greatly increased when the proposed algorithm of examination is used both at the disease onset and during the follow-up of patients with destructive pulmonary tuberculosis

2015-01-01

The present study is to investigate the relationship between microRNA (miR)-365 expression and the levels of interleukin (IL)-6 mRNA and protein in patients with active tuberculosis. From June 2011 to June 2014, 48 patients with active pulmonary tuberculosis induced by Mycobacterium tuberculosis were included in the study. In addition, 23 healthy subjects were enrolled as control. Macrophages were collected by pulmonary alveolus lavage. In addition, serum and mononuclear cells were isolated from peripheral blood. The levels of miR-365 and IL-6 in macrophages, mononuclear cells and serum were determined using quantitative real-time polymerase chain reaction. The protein expression of IL-6 in macrophages and mononuclear cells was measured using Western blotting, while that in serum was detected by enzyme-linked immunoabsorbent assay. Expression of IL-6 mRNA and protein was significantly enhanced in patients with active pulmonary tuberculosis. Increase of IL-6 protein concentration in serum was probably due to the release of IL-6 protein from mononuclear cells in the blood. In addition, miR-365 levels were significantly lowered in patients with active pulmonary tuberculosis. Up-regulated IL-6 expression in macrophages, mononuclear cells and serum in patients with active pulmonary tuberculosis is related to the down-regulation of miR-365, suggesting that miR-365 may regulate the occurrence and immune responses of active pulmonary tuberculosis via IL-6.

A photofluorographic mass survey of P-A chest had been done to the 13136 residents (male 6264, female 6872) in Jeonbug province, Korea for about 2 years from May 5, to Dec.19, 1978 and from Mar. 5, to Dec. 22, 1979. The results are as follows: 1. The prevalence rate of all active pulmonary tuberculosis is 5.3%. 2. The prevalence rate of male(8.8%) is 4.2 times higher than that of female (2.1%). 3. The prevalence rates of all old age groups above fifty years are higher than that of remainder under fifty years of age. Of these, 61-70 years old age group is highest in prevalence rate. 4. According to extent of active pulmonary tuberculosis, 77.5% is minimal, 15.4% is moderately advanced, and 7.1% is far advanced. Inactive pulmonary tuberculosis are 39 cases (0.3% to objective population). 5. In the incidence of the involved side, right side is about 2 times higher than the left, and involvement of both sides is increased in moderately and far advance pulmonary tuberculosis. In all pulmonary tuberculosis, one or both upper lung fields are most commonly involved. The incidences of cavity in moderately and far advanced pulmonary tuberculosis show no significant difference. 6. The incidences of other intrathoracic lesions are as follows: suspected hypertensive heart disease 2.4%, dextrocardia with situs inversus 0.04%, pleural calcification 0.4%, pleural thickening 0.2%, pleural effusion 0.1%, pneumonia 0.02%, bronchiectasis 0.1%, lung abscess 0.02%, C.O.P.D. 0.2%, suspected lung tumor 0.06%, pneumothorax 0.0076%, and suspected mediastinal tumor 0.02%

Background The prognosis, specifically the case fatality and duration, of untreated tuberculosis is important as many patients are not correctly diagnosed and therefore receive inadequate or no treatment. Furthermore, duration and case fatality of tuberculosis are key parameters in interpreting epidemiological data. Methodology and Principal Findings To estimate the duration and case fatality of untreated pulmonary tuberculosis in HIV negative patients we reviewed studies from the pre-chemotherapy era. Untreated smear-positive tuberculosis among HIV negative individuals has a 10-year case fatality variously reported between 53% and 86%, with a weighted mean of 70%. Ten-year case fatality of culture-positive smear-negative tuberculosis was nowhere reported directly but can be indirectly estimated to be approximately 20%. The duration of tuberculosis from onset to cure or death is approximately 3 years and appears to be similar for smear-positive and smear-negative tuberculosis. Conclusions Current models of untreated tuberculosis that assume a total duration of 2 years until self-cure or death underestimate the duration of disease by about one year, but their case fatality estimates of 70% for smear-positive and 20% for culture-positive smear-negative tuberculosis appear to be satisfactory.

2009-01-01

Full Text Available Evaluation of proliferative and IL-2-producing activity of peripheral blood lymphocytes wasperformed, using cultural methods, in patients with drug-sensitive and drug-resistant infiltrative pulmonary tuberculosis. The cell testing was performed at basal level and following in vitro stimulation with recombinant IL-2 and M. tuberculosis antigens. It was established that clinical course of infiltrative pulmonary tuberculosis, independently on drug sensitivity/resistance of the infectious pathogen, is accompanied by suppression of spontaneous lymphoproliferation. The levels of induced IL-2 production in drug-sensitive tuberculosis proved to be increased, whereas a reserve of IL-2-secreting reactivity of blood lymphocytes was lower than in drugresistant infection. Also, it was revealed that the level of lymphoproliferative response induced by IL-2, does not depend on clinical variant of tuberculosis, whereas stimulation of IL-2 production in blood lymphocytes is attained only in cases of drug-resistant tuberculosis variant.

Pakistan ranks eighth on the list of 22 high-burden tuberculosis (TB) countries in the world according to the World Health Organisation's (WHO) Global Tuberculosis Control 2009. Including other reasons the main cause is improper and late diagnosis of the disease. PCR may play an important role to control the disease with its rapid, sensitive and specific diagnosis. But in Pakistan due to lake of knowledge about this latest technique we are not using this technique appropriately. Clinicians still trust on conventional methods of TB diagnosis, which are time consuming or insensitive. The present study was arranged to highlight the importance of PCR in TB diagnosis in pulmonary and extra-pulmonary cases and its comparison with conventional methods. Methods: Samples obtained from 290 patients of suspected TB (pulmonary or extra-pulmonary) were subjected to ZN smear examination, LJ medium culture and PCR test by amplifying 541 bp fragment of Mycobacterium tuberculosis complex genome. The present prospective study is performed at Shalamar Hospital Lahore from November 2008 to November 2010. Results: A distinctly difference was observed in the test results done by PCR and other conventional techniques in pulmonary or extra-pulmonary tuberculosis samples (p<0.001). The sensitivity of different tests was 68.62% for PCR, 26.90% for LJ medium culture, and 14.14% for ZN smear examination (p<0.05). However, there was no significant difference between different tests as for as specificity was concerned. PCR test sensitivity in pulmonary and extra-pulmonary clinical samples was 78.34 and 61.76% respectively, being significantly higher (p<0.05) when compared with sensitivity of other tests. The mean detection time for M. tuberculosis was 25 days by LJ medium culture and less than 1 day by smear examination and PCR test. Conclusion: PCR test is more sensitive than ZN smear examination and LJ medium culture for the diagnosis of TB in pulmonary and extra-pulmonary clinical samples

2017-01-01

ABSTRACT Objective: To evaluate the prevalence of pulmonary function abnormalities and to investigate the factors affecting lung function in patients treated for pulmonary tuberculosis. Methods: A total of 214 consecutive patients (132 men and 82 women; 20-82 years of age), treated for pulmonary tuberculosis and followed at a local dispensary, underwent spirometry and plethysmography at least one year after treatment. Results: Pulmonary impairment was present in 102 (47.7%) of the 214 patients evaluated. The most common functional alteration was obstructive lung disease (seen in 34.6%). Of the 214 patients, 60 (28.0%) showed reduced pulmonary function (FEV1 below the lower limit of normal). Risk factors for reduced pulmonary function were having had culture-positive pulmonary tuberculosis in the past, being over 50 years of age, having recurrent tuberculosis, and having a lower level of education. Conclusions: Nearly half of all tuberculosis patients evolve to impaired pulmonary function. That underscores the need for pulmonary function testing after the end of treatment. PMID:28380187

In 20 normal cases and 39 pulmonary tuberculosis cases, regional pulmonary arterial blood flow measurement and lung perfusion scans by {sup 131}I-Macroaggregated albumin, lung inhalation scans by colloidal {sup 198}Au and spirometries by respirometer were done at the Radiological Research Institute. The measured lung function tests were compared and the results were as the following: 1) The normal distribution of pulmonary blood flow was found to be 54.5{+-}2.82% to the right lung and 45.5{+-}2.39% to the left lung. The difference between the right and left pulmonary arterial blood flow was significant statistically (p<0.01). In the minimal pulmonary tuberculosis, the average distribution of pulmonary arterial blood flow was found to be 52.5{+-}5.3% to the right lung and 47.5{+-}1.0% to the left lung when the tuberculous lesion was in the right lung, and 56.2{+-}4.4% to the right lung and 43.8{+-}3.1% to the left lung when the tuberculous lesion was in the left lung. The difference of pulmonary arterial blood flow between the right and left lung was statistically not significant compared with the normal distribution. In the moderately advanced pulmonary tuberculosis, the average distribution of pulmonary arterial blood flow was found to be 26.9{+-}13.9% to the right lung and 73.1{+-}13.9% to the left lung when the tuberculous lesion was more severe in the right lung, and 79.6{+-}12.8% to the right lung and 20.4{+-}13.0% to the left lung when the tuberculous lesion was more severe in the left lung. These were found to be highly significant statistically compared with the normal distribution of pulmonary arterial blood flow (p<0.01). When both lungs were evenly involved, the average distribution of pulmonary arterial blood flow was found to be 49.5{+-}8.01% to the right lung and 50.5{+-}8.01% to the left lung. In the far advanced pulmonary tuberculosis, the average distribution of pulmonary arterial blood flow was found to be 18.5{+-}11.6% to the right lung and 81

2017-01-01

Background: Tuberculosis (TB) in children is clearly linked to TB in adults therefore active household contact tracing is an important method of early diagnosis and treatment particularly in high-TB-burden countries. Objectives: To estimate the prevalence of TB among household contacts of children suffering from tuberculosis using active contact tracing and linking them to TB program for treatment. Subjects and Methods: A total of 125 children suffering from active tuberculosis (index cases)aged 12 years or less were randomly selected from the outpatient department of a tertiary care hospital of Hyderabad. Using their home address, all house hold members of the index cases (sharing one kitchen) were identified. The households were visited by a team including a doctor and the supported staff and were screened for TB using history, physical examination, sputum for AFB and X-ray of chest. Clinical suspects were divided in to two populations, equal to or less than 12 years of age and greater than this age. All suspected cases were brought to outpatient's department of the hospital where children were examined and diagnosed by pediatrician and adults were examined by the pulmonologist. Results: There were 125 children and 1365 household members. Prevalence of active TB in adult household contacts was 8.1 percent and among children was 5.7 percent. Mother, father, grand parents or siblings were the source of disease spread in children. Family history of TB was present in 95 percent (pulmonary 78 percent, extra-pulmonary 22 percent). Conclusion: Tuberculosis in children is mostly spreading from household member hence deeply required to undertake active contact tracing in each new case that is diagnosed or being treated. Policy message: National and Provincial TB programs should advocate and undertake active screening of all household contacts of all TB cases. (author)

Human immunodeficiency virus (HIV) epidemic has undoubtedly increased the incidence of tuberculosis (TB) globally, posing a formidable global health challenge affecting 1.2 million cases. Pulmonary TB assumes utmost significance in the programmatic perspective as it is readily transmissible as well as easily diagnosable. HIV complicates every aspect of pulmonary tuberculosis from diagnosis to treatment, demanding a different approach to effectively tackle both the diseases. In order to control these converging epidemics, it is important to diagnose early, initiate appropriate therapy for both infections, prevent transmission and administer preventive therapy. Liquid culture methods and nucleic acid amplification tests for TB confirmation have replaced conventional solid media, enabling quicker and simultaneous detection of mycobacterium and its drug sensitivity profile Unique problems posed by the syndemic include Acquired rifampicin resistance, drug-drug interactions, malabsorption of drugs and immune reconstitution inflammatory syndrome or paradoxical reaction that complicate dual and concomitant therapy. While the antiretroviral therapy armamentarium is constantly reinforced by discovery of newer and safer drugs every year, only a few drugs for anti tuberculosis treatment have successfully emerged. These include bedaquiline, delamanid and pretomanid which have entered phase III B trials and are also available through conditional access national programmes. The current guidelines by WHO to start Antiretroviral therapy irrespective of CD4+ cell count based on benefits cited by recent trials could go a long way in preventing various complications caused by the deadly duo. This review provides a consolidated gist of the advancements, concepts and updates that have emerged in the management of HIV-associated pulmonary TB for maximizing efficacy, offering latest solutions for tackling drug-drug interactions and remedial measures for immune reconstitution inflammatory

Cystic change associated with pulmonary tuberculosis is rarely encountered, and few reports are available on the radiologic findings of pulmonary tuberculosis presenting as multiple cystic lesions associated with consolidation or bronchohematogenous nodules. The cystic lesions in our pulmonary tuberculosis patient occurred during steroid treatment without antituberculous chemotherapy and progressively increased in size, but subsequently became smaller after the initiation of antituberculous chemotherapy. Herein, we report the chest radiographic and computed tomographic findings of cystic change in pulmonary tuberculosis in an immunocompetent adult

• BACKGROUND: Despite recent technologic improvements in identifying mycobacterium tuberculosis, we are still facing problems in rapid diagnosis of tuberculosis. The objective of this study is to determine the diagnostic value of a new rapid screening test (Patho-TB™ for diagnosis of pulmonary tuberculosis.
• METHODS: Between September 2006 to August 2007, 178 patients were enrolled in the study who were finally classified into two groups; a group of documented pulmonary tuberculosis (n = 67 and a group of non-tuberculous pulmonary infection (n = 111. Patho-TB™ test, Ziehl-Neelsen staining and culture were done on all specimens.
• RESULTS: Of all, 43 patients with pulmonary tuberculosis were sputum smear positive for acid fast bacilli and the rest were smear negative. Mean age of the patients was 59.8 ± 16.1 years and 44% of them were men. The results of Patho- TB™ test were positive in 40 of smear positive and 20 of smear negative tuberculous patients and 33 cases of nontuberculous control group. The sensitivity, specificity, positive and negative predictive values and accuracy of Patho- TB™ test were estimated 89.5%, 70.2%, 64.5%, 91.7% and 77.5%, respectively.
• CONCLUSIONS: According to the present study it would be suggested that Patho-TB™ test could be a rapid and inexpensive method for diagnosis of pulmonary tuberculosis, given by its high sensitivity and negative predictive value. Concerning the high number of false positive results, using a confirmatory diagnostic procedure is mandatory.

Pulmonary artery aneurysms constitute 50%) of cases, however, pulmonary artery aneurysm is a rare sequelae of pulmonary tuberculosis reported in about 5% of patients with chronic cavitary tuberculosis on autopsy. The natural history of this potentially fatal condition remains poorly understood and guidelines for optimal management are controversial. A 24-year-old man, a nursing student of African descent, was referred to us from an up-country regional hospital with a 4-week history of recurrent episodes of breathlessness, awareness of heartbeats and coughing blood 3 weeks after completing a 6-month course of anti-tuberculosis drugs. A physical examination revealed conjuctival and palmar pallor but there were no stigmata of connective tissue disorders, systemic vasculitides or congenital heart disease. An examination of the cardiovascular system revealed accentuated second heart sound (S 2 ) with early diastolic (grade 1/6) and holosystolic (grade 2/6) murmurs at the pulmonic and tricuspid areas respectively. Blood tests showed iron deficiency anemia, prolonged bleeding time, and mild hyponatremia. A chest radiograph revealed bilateral ovoid-shaped perihilar opacities while a computed tomography scan showed bilateral multiple pulmonary artery pseudoaneurysms with surrounding hematoma together with adjacent cystic changes, consolidations, and tree-in-bud appearance. Our patient refused to undergo surgery and died of aneurismal rupture after 9 days of hospitalization. The presence of intractable hemoptysis among patients with tuberculosis even after completion of anti-tuberculosis course should raise an index of suspicion for pulmonary artery aneurysm. Furthermore, despite of its rarity, early recognition and timely surgical intervention of pulmonary artery aneurysm is crucial to reducing morbidity and preventing the attributed mortality.

To evaluate the diagnostic accuracy of bronchoscopy in patients with clinical or radiological suspicion of tuberculosis who were unable to produce sputum or with negative sputum smear microscopy results. A prospective cross-sectional study involving 286 patients under clinical or radiological suspicion of having pulmonary tuberculosis and submitted to bronchoscopy-BAL and transbronchial biopsy (TBB). The BAL specimens were submitted to direct testing and culture for AFB and fungi, whereas the TBB specimens were submitted to histopathological examination. Of the 286 patients studied, 225 (79%) were diagnosed on the basis of bronchoscopic findings, as follows: pulmonary tuberculosis, in 127 (44%); nonspecific chronic inflammation, in 51 (18%); pneumocystis, fungal infections, or nocardiosis, in 20 (7%); bronchiolitis obliterans organizing pneumonia, alveolites, or pneumoconiosis, in 14 (5%); lung or metastatic neoplasms, in 7 (2%); and nontuberculous mycobacterium infections, in 6 (2%). For the diagnosis of tuberculosis, BAL showed a sensitivity and a specificity of 60% and 100%, respectively. Adding the TBB findings significantly increased this sensitivity (to 84%), as did adding the post-bronchoscopy sputum smear microscopy results (total sensitivity, 94%). Minor post-procedure complications occurred in 5.6% of the cases. Bronchoscopy is a reliable method for the diagnosis of pulmonary tuberculosis, with low complication rates. The combination of TBB and BAL increases the sensitivity of the method and facilitates the differential diagnosis with other diseases.

Objectives: To determine the association between cigarette smoking and pulmonary tuberculosis. Methodology: In this retrospective study which was carried out in Razi hospital, in Ahvaz a city southwest Iran, medical charts of patients with tuberculosis between 2005 and 2007 were reviewed. Sixty one patients aged 15-96 years with documented pulmonary tuberculosis (smear positive) were selected as cases and 122 age and sex matched persons without tuberculosis(patients hospitalized in surgery and orthopedic wards) were selected randomly as controls. Data on smoking status, quantity of cigarette smoked, and duration of smoking was collected from medical charts. The data in the two groups were statistically compared with SPSS version 16. The chi square test was used to compare the frequency of cigarette smoking in two groups. Ninety-five percent confidence intervals were calculated when appropriate. Differences with a P value of <0.05 were considered significant. Results: Of total 61 case, 42 (68.9%) were smoker, while, of total 122 controls 22(18%) were smoker. The estimated odds ratio (OR) of the relation between smoking and tuberculosis was 10.1 [(95% confidence interval (CI) 4.3 to 23.5), P<0.001]. The mean of pocket - year of smoked cigarette (20/pocket) in cases and controls were 15.9 +- 13.7 and 13.5 +- 9.1, respectively (P=0.5). Conclusion: This study showed that pulmonary tuberculosis is associated to cigarette smoking. The association is not dose-dependent. Smoking may be a risk factor for TB acquisition. (author)

Emerging evidence shows that microRNAs (miRNAs) play an important role in pathogen-host interactions. Circulating miRNAs have been repeatedly and stably detected in blood and hold promise to serve as molecular markers for diverse physiological and pathological conditions. To date, the relationship between circulating miRNAs and active pulmonary tuberculosis (TB) has not been reported. Using microarray-based expression profiling followed by real-time quantitative PCR validation, the levels of circulating miRNAs were compared between patients with active pulmonary tuberculosis and matched healthy controls. The receiver operating characteristic curve was used to evaluate the diagnostic effect of selected miRNA. Bioinformatic analysis was used to explore the potential roles of these circulating miRNAs in active pulmonary tuberculosis infection. Among 92 miRNAs significantly detected, 59 miRNAs were downregulated and 33 miRNAs were upregulated in the TB serum compared to their levels in the control serum. Interestingly, only two differentially expressed miRNAs were increased not only in the serum but also in the sputum of patients with active pulmonary tuberculosis compared to the levels for the healthy controls. Upregulated miR-29a could discriminate TB patients from healthy controls with reasonable sensitivity and specificity. A number of significantly enriched pathways regulated by these circulating miRNAs were predicted, and most of them were involved in acute-phase response, inflammatory response, and the regulation of the cytoskeleton. In all, for the first time our results revealed that a number of miRNAs were differentially expressed during active pulmonary tuberculosis infection, and circulating miR-29a has great potential to serve as a marker for the detection of active pulmonary tuberculosis infection.

Patients with pulmonary tuberculosis are likely to develop pulmonary impairment after tuberculosis (PIAT). The stability of PIAT and the relationship of PIAT to the duration of delay in tuberculosis diagnosis and treatment have not been fully characterized. We performed serial pulmonary function tests (PFTs) in a cohort treated for pulmonary tuberculosis after 20 weeks of tuberculosis therapy and again on or after treatment completion to determine the stability of PIAT. PFTs were compared with the duration of delay in tuberculosis diagnosis and treatment, as well as other demographic variables. The median duration between the first and second tests was 15 (interquartile range 9-34) weeks. The mean change in FVC was -0.02l (95% confidence interval [CI] -0.09, 0.06), and the % predicted was -0.02 (95% CI -2.17, 2.12). FEV1 changes were 0l (95% CI -0.05, 0.06), and the % predicted was -0.11 (95% CI -1.82, 1.60). PIAT was not related to the duration of delay in tuberculosis diagnosis or treatment, age or smoking. PIAT was not associated with the duration of delay in tuberculosis diagnosis and treatment and did not significantly change during follow-up. These data demonstrate that, for many individuals, the completion of tuberculosis treatment is the beginning, not the end, of their tuberculosis illness. Published by Elsevier Ltd.

Objective: To study the imaging findings of disseminated pulmonary tuberculosis in patients with acquired immunodeficiency syndrome (AIDS). Methods: X-ray and multi-slice CT (MSCT) data from 33 AIDS patients with disseminated pulmonary tuberculosis confirmed by clinical manifestations and laboratory tests were analyzed retrospectively. Results: Thirty patients underwent initial chest radiography examination, 29 patients showed abnormal appearances, including bilateral disseminations in 21 patients and unilateral multiple disseminations in 8 patients. All patients underwent MSCT examination, 26 patients showed bilateral disseminations and 7 patients showed unilateral multiple disseminations. The abnormal pulmonary appearances included nodule (n = 25), miliary nodule (n = 22), air-space consolidation (n = 22), cavity (n = 11), fibrosis (n = 7), ground-glass opacity (n = 7), pneumatocele (n = 4), calcification (n = 2). There were 20 patients with more than 3 abnormal appearances and 13 patients with one or two abnormal appearances. The extra-pulmonary tuberculosis included pleural effusion (n = 33), lymphadenopathy (n = 30), intestinal tuberculosis (n = 3), splenic tuberculosis (n = 1) and cerebral tuberculosis (n = 1). Conclusion: Disseminated pulmonary tuberculosis should be highly suspected in AIDS patients with diffused nodules, miliary nodules, air-space consolidations or multiple cavities, accompanied with pleural effusion and lymphadenopathy.

Full Text Available Co-infection of visceral leishmaniasis and pulmonary tuberculosis are increasing public health problem in eastern region of country. A large number of clinical cases of leishmaniasis and tuberculosis have been reported in Sudan. Such type of co-infections lead to decreased host ’s immune system. This is a case report of 48 years old male with visceral leishmaniasis and pulmonary tuberculosis. He arrived at hospital with complaints of fever with rigor, abdominal pain, weakness, loss of appetite, yellowish discoloration of urine and sclerosis at lower back. Bone marrow aspiration cytology revealed the presence of Leishmania donovani bodies (2+. His treatment was initiated with amphotericin B deoxycholate (inj. Fungizone 15 infusions on alternate days with 5% dextrose. He had 20 years past history of pulmonary tuberculosis. His chest X-ray showed increased bronchovascular marking encysted pleural effusion on lower segment of right lung. Ultrasonography guided fine needle aspiration cytology of pleural fluid for protein, sugar, lactate dehydrogenase, adenosine deaminase, cell type and cell count. Cytological reports confirmed pulmonary tuberculosis. Antitubercular therapy (four drug regimen: rifampicin, isoniazid, ethambutal, and pyrazinamide was started. Co-infection of visceral leishmaniasis and pulmonary tuberculosis is a real threat in developing countries. There is a need of cost effective diagnostic and therapeutic facilities for these co-infections.

Objective: To describe tomographic findings of lobar consolidation as early manifestation of primary pulmonary tuberculosis. Materials and methods: The present study was developed at Hospital Municipal Jesus, Rio de Janeiro, RJ, Brazil, in the period between 2002 and 2006, retrospectively evaluating tomographic findings in four children aged from 3 to 14 months with lobar consolidation as an early manifestation of primary pulmonary tuberculosis. Results: The most frequently found radiological pattern was lobar consolidation with calcifications, cavitation and intermingle necrotic areas, associated with bulging fissure. Signs of bronchogenic dissemination and lymph node enlargement were observed in all of the four children. Consolidation with a pseudotumor aspect and masslike effect was observed in one case. Conclusion: The cases included in the present study have demonstrated that primary pulmonary tuberculosis manifested as lobar consolidation presents typical tomographic images such as cavitation, hypodense areas and calcifications intermingled with consolidation. The association with lymph node enlargement with central necrosis and signs of bronchogenic dissemination reinforce the diagnosis of tuberculosis. (author)

Background People who are newly diagnosed with pulmonary tuberculosis (TB) typically receive a standard first-line treatment regimen that consists of two months of isoniazid, rifampicin, pyrazinamide, and ethambutol followed by four months of isoniazid and rifampicin. Fixed-dose combinations (FDCs) of these drugs are widely recommended. Objectives To compare the efficacy, safety, and acceptability of anti-tuberculosis regimens given as fixed-dose combinations compared to single-drug formulations for treating people with newly diagnosed pulmonary tuberculosis. Search methods We searched the Cochrane Infectious Disease Group Specialized Register; the Cochrane Central Register of Controlled Trials (CENTRAL, published in the Cochrane Library, Issue 11 2015); MEDLINE (1966 to 20 November 2015); EMBASE (1980 to 20 November 2015); LILACS (1982 to 20 November 2015); the metaRegister of Controlled Trials; and the World Health Organization International Clinical Trials Registry Platform (WHO ICTRP), without language restrictions, up to 20 November 2015. Selection criteria Randomized controlled trials that compared the use of FDCs with single-drug formulations in adults (aged 15 years or more) newly diagnosed with pulmonary TB. Data collection and analysis Two review authors independently assessed studies for inclusion, and assessed the risk of bias and extracted data from the included trials. We used risk ratios (RRs) for dichotomous data and mean differences (MDs) for continuous data with 95% confidence intervals (CIs). We attempted to assess the effect of treatment for time-to-event measures with hazard ratios and their 95% CIs. We used the Cochrane 'Risk of bias' assessment tool to determine the risk of bias in included trials. We used the fixed-effect model when there was little heterogeneity and the random-effects model with moderate heterogeneity. We used an I² statistic value of 75% or greater to denote significant heterogeneity, in which case we did not perform a

Pulmonary tuberculosis (TB) is a common worldwide lung infection. The radiological features show considerable variation, but in most cases they are characteristic enough to suggest the diagnosis. Classically, tuberculosis is divided into primary, common in childhood, and postprimary, usually presenting in adults. The most characteristic radiological feature in primary tuberculosis is lymphadenopathy. On enhanced CT, hilar and mediastinal nodes with a central hypodense area suggest the diagnosis. Cavitation is the hallmark of postprimary tuberculosis and appears in around half of patients. Patchy, poorly defined consolidation in the apical and posterior segments of the upper lobes, and in the superior segment of the lower lobe is also commonly observed. Several complications are associated with tuberculous infection, such as hematogenous dissemination (miliary tuberculosis) or extension to the pleura, resulting in pleural effusion. Late complications of tuberculosis comprise a heterogeneous group of processes including tuberculoma, bronchial stenosis bronchiectasis, broncholithiasis, aspergilloma, bronchoesophageal fistula and fibrosing mediastinitis. Radiology provides essential information for the management and follow up of these patients and is extremely valuable for monitoring complications.

Dental laboratory technicians are at risk of developing occupational respiratory diseases due to exposure to various potentially toxic substances in their working environment. Since 1939, few cases of silicosis among dental technician have been reported. We illustrate a 38 year-old female, who worked in a dental laboratory for 20 years, initially treated as pulmonary tuberculosis and chronic necrotising aspergillosis without much improvement. Computed tomography guided lung biopsy and bronchoscopic transbronchial lung biopsy were performed. Lung tissue biopsies showed presence of refractile dental materials within the areas of histiocyte proliferation. The diagnosis of dental technician pneumoconiosis was obtained and our patient underwent pulmonary rehabilitation. This case highlights the importance of obtaining a detailed occupational history in tuberculosis endemic area, as pulmonary tuberculosis is a great mimicker of other respiratory diseases.

Lung cancer and pulmonary tuberculosis (TB) comorbidity is a clinical problem that presents a challenge for the diagnosis and treatment of both diseases. To clarify the clinical and survival characteristics of cases with both lung cancer and active pulmonary TB. From 2008 to 2013, 3350 TB patients admitted to the TB Department of the Chest Diseases Hospital of Izmir, Turkey, were evaluated. In 38 (1.1%) male patients, lung cancer and TB were found to coexist. Almost all of the patients were diagnosed at Stage III (n = 14, 36.8%) or IV (n = 17, 44.7%) lung cancer, whereas four (10.6%) had Stage II and three (7.9%) had Stage I disease. Squamous cell lung cancer was the predominant histology (n = 23, 60.7%). The median overall survival among patients was 13.4 months (95%CI 8.09-18.8). One-year survival rates for patients with Stages I, II, III and IV were respectively 100%, 75%, 57% and 40%. The present study demonstrates that lung cancer combined with active pulmonary TB most frequently presents as squamous cell carcinoma, with a male predominance. The overall survival of lung cancer patients did not change even with concomitant active TB.

Objective: The chest radiography and TCT findings in children who had contacted with adult family members with active pulmonary tuberculosis were compared. The contributions of thoracic computed tomography to the diagnosis of tuberculosis were investigated. Methods and material: The children who were 0-16 years old (n=173) and children of families with an adult member which was diagnosed as pulmonary tuberculosis were evaluated. The children were considered in two groups based on the absence (n=125) or presence (n=48) of complaints and/or ambiguous symptoms such as lack of appetite, mild cough, sweating, history of lung infection, low body weight and those with suspicious chest radiography findings (12 cases) were included in this study. Asymptomatic patients (n=125) did not undergo TCT. Patients who had positive PPD skin tests only received isoniazid. If the TCT demonstrated enlarged lymph nodes or parenchymal lesions, minimally active pulmonary tuberculosis was diagnosed and antituberculous treatment was given. Results and discussions: TCT revealed lymph node enlargement or parenchymal lesions in 39 children (81.2%). Of the 12 children whose CXRs revealed suspicious lymph node enlargement and/or infiltration, five had normal findings in TCT whereas the initial findings were confirmed in the remaining seven. These data suggest that there is a correlation between the presence of ambiguous symptoms in exposed children and TCT findings; chest radiography and TCT findings do not yield parallel findings. All the patients who received anti-TB treatment were resolved in the control examinations. Conclusion: In this study there is a correlation between presence of ambiguous symptoms and TCT findings, but the chest radiography and TCT findings do not yield harmony in exposed children with ambiguous symptoms (suspicious tuberculosis cases). These observations should be considered in children with symptoms similar to those of exposed children, but with no definite history of

Full Text Available Background: Uncontrolled blood glucose, which marked by high level of HbA1c, increases risk of pulmonary TB because of cellular immunity dysfunction. This study aimed to analyze profile of glycated hemoglobin, antioxidant vitamins status and cytokines levels in active pulmonary TB patients. Methods: This was a cross sectional study, conducted at Pulmonary Diseases Center Semarang City, Indonesia. Study subject consisted of 62 pulmonary TB patients, diagnosed with positive acid fast bacilli and chest X-ray. ELISA was used to measure IFN-γ and IL-12. Status of antioxidant vitamins was determined by concentration of vitamin A and E using HPLC. Blood glucose control was determined by HbA1c concentration (HbA1c ≥7% is considered as uncontrolled. Results: A significant difference of age between pulmonary tuberculosis patients with normal and uncontrolled blood glucose (p = 0.000 was showed, while all other characteristics (sex, education, occupation did not differ with p = 0.050, 0.280, 0.380 respectively. Mean HbA1c was 7.25 ± 2.70%. Prevalence of uncontrolled glucose among pulmonary TB patients was 29%. Levels of IFN-γ and IL-12 did not differ according to HbA1c concentration (p = 0.159 and p = 0.965 respectively. Pulmonary tuberculosis patients with uncontrolled blood glucose has higher vitamin E (p = 0.006, while vitamin A did not differ significantly (p = 0.478. Conclusions: This study supports the importance of performing diabetes screening among pulmonary TB patients. Further study needs to be done to determine the feasibility of TB-DM co-management.

The outcome of the chemotherapy for pulmonary, extraplumonary and disseminated tuberculosis is not well documented, especially in developing countries. This study assessed tuberculosis treatment outcome, cure-to-treatment ratio and mortality among all types of tuberculosis patients in a tertiary care setting in Saudi Arabia. All cases diagnosed and treated for active Mycobacterium tuberculosis infection between 1991 and 2000 were included retrospectively. Data collected included type of tuberculosis involvement, treatment outcome, relapse and co-morbidities. Over a ten-year period, 535 case of tuberculosis were diagnosed and treated. Isolated pulmonary tuberculosis was identified in 141 cases (26.4%), extrapulmonary tuberculosis in 339 cases (63.3%). Co-morbidities were noted in 277 (52%) patients. Immunosuppression was found in 181 (34%) cases. The cure rate was 82%. The cure-to-treatment ratio was 86% in extrapulmonary tuberculosis and 65% in disseminated tuberculosis. Overall mortality was 18%. Disseminated tuberculosis had the highest mortality (34.9%), followed by pulmonary (21.8%), the extrapulmonary tuberculosis (13.6%). Forty-seven percent of all mortalities were directly related to tuberculosis. Relapse was documented in 14 out of 349 patients (4%) who had 24 months of follow-up. Despite tertiary care support, complicated tuberculosis carries a high mortality. Earlier diagnosis and complete appropriate chemotherapy are essential for improved outcome. (author)

It was established that there is a great number works dedicated to the lipid peroxidation and antioxidant protective system in various pathological conditions of the respiratory system, including pulmonary tuberculosis in children and teenagers today. Oxidative modification proteins products are the earliest markers of oxidative stress in patients. There is no information on the oxidative modification of proteins in children and teenagers suffering from pulmonary tuberculosis in the literature. The study of oxidative modification of proteins will facilitate the development of more efficient new diagnosis methods and pathogenetic treatment of children and teenagers with pulmonary tuberculosis, that will increase the treatment effectiveness.

To evaluate the sensitivity of gastric lavage specimen for observation of acid fast bacilli and isolation of mycobacterium in patients proved to be suffering from pulmonary tuberculosis. A total number of 886 hospitalized patients in different hospitals of Urmia City were tested for pulmonary tuberculosis. Fifty-three patients were eventually enrolled in the study and one gastric lavage specimen was taken from each patient. Among these fifty three, 44 had positive gastric lavage results and 43 were positive on culture, while both positive results of smear and culture were matched in all patients proved to be suffering from pulmonary tuberculosis. The highest positive rate was in 20 to 49 and 20 to 29 years for the culture and smear respectively but the lowest culture positive rate was in those patients who were in children and those over 60 years of age. Gastric lavage can be a valuable alternative specimen instead of sputum for diagnosis of tuberculosis in children and elderly patients if both smear and culture results are applied. (author)

Presentation of tuberculosis (TB) in pregnancy may be atypical with diagnostic challenges. Two patients with complicated pregnancy outcomes, foetal loss and live premature delivery at 5 and 7 months of gestation, respectively, and maternal loss, were diagnosed with pulmonary TB. Chest radiography and computed tomography showed widespread reticuloalveolar infiltrates and consolidation with cavitations, respectively. Both patients were Human Immunodeficiency Virus (HIV) seronegative and sputum smear negative for TB. Sputum GeneXpert MTB/Rif (Xpert MTB/RIF) was positive for Mycobacterium tuberculosis. To strengthen maternal and childhood TB control, screening with same-day point-of-care Xpert MTB/RIF is advocated among both HIV positive pregnant women and symptomatic HIV negative pregnant women during antenatal care in pregnancy and at puerperium.

Tl-201 lung uptake in 74 patients (85 lesions) and pulmonary perfusion in 105 patients were studied to evaluate clinical usefulness of Tl-201 lung uptake and perfusion lung scintigraphy in pulmonary tuberculosis, using a scintillation camera with a mini-computer system. As indices of Tl-201 lung uptake, lung (lesion) to upper mediastinum uptake ratio (L/M) and visual grading were used. L/M in pulmonary tuberculosis was 1.96±0.66, which was significantly larger than 1.04±0.24 in healthy controls and lower than that in heart diseases with left heart failure and idiopathic interstitial pneumonia, and showed no significant differences with that in acute pneumonia, pyothorax, primary lung cancer and malignant mediastinal tumor. L/M in pulmonary tuberculosis did not correlate with CRP, erythrocyte sedimentation rate, Gaffky number of sputum and body temperature. It correlated with the type of pulmonary tuberculosis according to the Gakken Classification reflecting the disease activity. It was larger in the exudative type, caseo-infiltrative one, disseminated one, one with cavity in infiltrative lesion than the fibro-caseous one. On perfusion lung scintigram, impairment of pulmonary perfusion larger than area of the entire unilateral lung was observed in 68 cases (64.8%). Area of hypoperfused lung field, which correlated with % vital capacity (r=0.60, p=0.0002) and PaO 2 (r=0.39,p=0.0024), was significantly larger in patients with silicosis and those with bilateral pleural involvements such as pleural callosity than in those with type III according to the Gakkai Classification. Most of the patients showed decreased pulmonary perfusion and Tl-201 accumulation of which grade reflects the disease activity in active tuberculous lesion. Patients with miliary tuberculosis and those with silicotuberculosis showed diffuse Tl-201 accumulation in the both lungs. Tl-201 lung scintigraphy seems to be useful for visualizing active tuberculous lesions, particularly the ones that

To evaluate the effectiveness of arterial embolization in reducing hemoptysis in pulmonary tuberculosis, and rebleeding factors after embolization. Fifty-nine patients with massive or recurrent hemoptysis from pulmonary tuberculosis were underwent percutaneous transcatheter embolotherapy and thirteen were subsequently operated on. In 46 patients, we retrospectively analyzed on plain chest PA the extent of pulmonary tuberculosis lesions, the period from initial diagnosis to embolization, and angiographic findings. The extent of lesions shown on plain chest PA were classified into minimal, moderately advanced, and far advanced. If there was no evidence of rebleeding after the first embolization,this was regarded as initial success in the control of hemoptysis. Angiographic findings were classified into hypervascularity, shunt, aneurysmal dilatation, and extravasation. Using the chi-square test, differences in these findings between rebleedig and non-rebleeding cases were anlysed. Immediate control of hemoptysis was achieved in 27 (58.7%) of 46 patients. Hemoptysis recurred in 19 (41.3%) of 46 patients followed up. Rebleeding cases showed more nonbronchial systemic collateral vessels and shunt than non-rebleeding cases (p<0.05). More advanced lesions of pulmonary tuberculosis on plain chest PA showed an increased rebleeding rate after embolization, but this was not statistically significant. There was no correlation between the period from initial diagnosis of pulmonary tuberculosis to embolization and the rate of rebleeding. But the longer the period, the greater the number of nonbronchial systemic collateral vessels. In cases with more advanced lesions of pulmonary tuberculosis on plain chese PA and a long period from initial diagnosis of pulmonary tuberculosis to embolization, angiographic findings showed numerous nonbronchial systemic collateral vessels but increases in the rebleeding rate were statistically not significant. The greater the number of nonbronchial

Tuberculosis is an infectious disease which caused by Mycobacterium tuberculosis (M. tuberculosis) that infected numerous organ especially the lung. A person’s immunity is very affecting for a person exposed to pulmonary tuberculosis. T-helper-1 cell (Th1) is very influential in the immune system especially in interfering intracellular bacterial infection. One of the cytokines known produced by Th1 cell is interferon gamma (IFN-γ) which is in eliminating M. tuberculosis. The study aims to identify the association between level of IFN-γ and AFB positivity in pulmonary tuberculosis patients in Medan. It is a case-control study. The subjects of the study were 60 new cases of pulmonary tuberculosis with AFB sputum smear- positive that never received ATT consisting 20 cases AFB (+1), 20 cases AFB (+2) and 20 cases AFB (+3).Samples were plasma collected from the venous blood of pulmonary tuberculosis patients. The plasma then underwent laboratory assay with ELISA techniques. Independent t-test was p<0.05 considered significant. Level of IFN-γ in TB AFB (+1) is higher than TB AFB (+2) and (+3), with thesignificant statistical result (p=0.001).

Objective: To explore the value of spiral CT in the diagnosis of atypical pulmonary nodules. Methods: CT, clinic and histopathologic data of 72 patients with atypical pulmonary nodules confirmed by surgical resection in 41 cases and/or biopsy in 31 cases were retrospectively analyzed. Results: CT scans demonstrated slight lobulation in 34 cases, irregular margin in 50 cases, long speculate in 10 cases, air-bronchogram in 2 case, vacuole in 2 case. 38 pulmonary cancer, 22 pulmonary tuberculosis and 12 pulmonary inflammatory pseudotumors were diagnosed with spiral CT. However, 30 pulmonary cancer, 30 pulmonary tuberculosis and 12 pulmonary inflammatory pseudotumors were confirmed by histopathology. The overall accurate diagnostic rate of pulmonary cancer was 66.7% (20/30), pulmonary tuberculosis was 60%(18/30), pulmonary inflammatory pseudotumors was 16.7%(2/12). 40 cases were diagnosed correctly and 32 cases were misdiagnosed with CT in 72 cases of atypical pulmonary nodules. The misdiagnostic rate of CT was 44.4%. 10 cases of lung cancer were misdiagnosed, including 4 cases of tuberculosis (long speculate or irregular margin) and 6 cases of inflammatory pseudotumors (irregular margin or long speculate or air-bronchogram). 12 cases of tuberculosis were misdiagnosed, including 8 cases lung cancer (slight lobulation) and 4 cases of inflammatory pseudotumors (slight lobulation). 10 cases inflammatory pseudotumor were misdiagnosed as lung cancer (slight lobulation). Conclusion: Spiral CT was very useful in the localization and morphological describing, but difficult in qualitative diagnosing of atypical pulmonary nodules, exactly diagnosis was relied on surgery and biopsy.

Full Text Available Role of microRNA (miRNA has been highlighted in pathogen-host interactions recently. At present, their role in active pulmonary tuberculosis is unknown. The aim of the study was to delineate miRNA expression in sputum supernatant of patients with active pulmonary tuberculosis. Expression of miRNAs was evaluated by microarray analysis and differentially expressed miRNAs were validated by RT-qPCR. Secreted cytokines TNF-α and IL-6 were measured by ELISA. We found that 95 miRNAs were differentially expressed between tuberculosis group and controls. More miRNAs (52 out of 95 miRNAs were underexpressed than overexpressed during tuberculosis infection. Overexpression of miR-3179, miR-147 and underexpression of miR-19b-2* in TB group compared with controls were confirmed in the validation cohort. TNF-α and IL-6 levels were not significantly altered between TB group and controls. For the first time, differential expression of miRNAs in sputum was found in active pulmonary tuberculosis. The study provides rationale for identifying the role of miRNAs in the pathogenesis of pulmonary tuberculosis and indicates potential for miRNA-based therapeutic strategies.

Objective: Respiratory infections constitute a major cause of morbidity and mortality in solid organ transplant recipients. The incidence of pulmonary tuberculosis is high among such patients. On imaging, tuberculosis has various presentations. Greater understanding of those presentations could reduce the impact of the disease by facilitating early diagnosis. Therefore, we attempted to describe the HRCT patterns of pulmonary tuberculosis in lung transplant recipients. Methods: From two hospitals in southern Brazil, we collected the following data on lung transplant recipients who developed pulmonary tuberculosis: gender; age; symptoms; the lung disease that led to transplantation; HRCT pattern; distribution of findings; time from transplantation to pulmonary tuberculosis; and mortality rate. The HRCT findings were classified as miliary nodules; cavitation and centrilobular nodules with a tree-in-bud pattern; ground-glass attenuation with consolidation; mediastinal lymph node enlargement; or pleural effusion. Results: We evaluated 402 lung transplant recipients, 19 of whom developed pulmonary tuberculosis after transplantation. Among those 19 patients, the most common HRCT patterns were ground-glass attenuation with consolidation (in 42%); cavitation and centrilobular nodules with a tree-in-bud pattern (in 31.5%); and mediastinal lymph node enlargement (in 15.7%). Among the patients with cavitation and centrilobular nodules with a tree-in-bud pattern, the distribution was within the upper lobes in 66.6%. No pleural effusion was observed. Despite treatment, one-year mortality was 47.3%. Conclusions: The predominant HRCT pattern was ground-glass attenuation with consolidation, followed by cavitation and centrilobular nodules with a tree-in-bud pattern. These findings are similar to those reported for immunocompetent patients with pulmonary tuberculosis and considerably different from those reported for AIDS patients with the same disease. (author)

To evaluate the CT spectrum of pulmonary tuberculosis, we reviewed CT of the chest in 80 adult patients with active pulmonary tuberculosis who had not been treated for tuberculosis. Main patterns seen in patients with active tuberculosis were: (1) nodular shadow (56%), (2) confluent consolidation (15%), and (3) round consolidation (16%). Other CT patterns were: (1) miliary tuberculosis (n=4), (2) pleural effusion only (n=4), and (3) normal chest (n=2). Major features seen at CT included segmental distribution (97%), satellite lesions (86%), single cavity in each cavitary lesion (95%), ectatic change of the bronchi, tendency of distortion or contraction.

The introduction of flexible bronchoscope has revolutionized the field of pulmonary medicine and is a standard instrument used for diagnostic purpose. A retrospective analysis of the clinico-radiological profile, indication, biopsy procedure and complications, for patients undergoing bronchoscopy at one of the respiratory unit at a tertiary care center in India. Retrospective analysis of 712 bronchoscopies was done in regard to demographic profile, clinical and radiological presentation and diagnostic indication. The results were analyzed on basis of bronchoscopy inspection and histopathological specimen obtained from transbronchial (TBLB), endobronchial biopsy (EBLB) and cytology specimen by transbronchial needle aspiration (TBNA). Furthermore, diagnostic yield of each biopsy procedure and their combination was evaluated. Of 712 patients undergoing bronchoscopy, the pathological diagnosis was achieved in 384 (53.93%). Of 384 diagnosed cases, the clinic-radio-pathological diagnosis of pulmonary tuberculosis in 88 (22.19%), interstitial lung disease (ILDs) in 226 (58.85%), and lung cancer in 70 (18.22%) cases. Of 116 sputum smear negative tuberculosis patients, 88 (75.86%) were diagnosed to be pulmonary tuberculosis; the contribution of BAL being 71.59%. Of 226 ILDs, sarcoidosis was most common 148/226 (65.48%). Among 70 lung cancer diagnosed cases, squamous cell carcinoma was most common (54.28%). The results from current study reemphasizes on the diagnostic utility as well as safety of the bronchoscopy procedure. Copyright © 2015 Tuberculosis Association of India. Published by Elsevier B.V.

The contrast enhanced CT findings in 14 patients with active tuberculosis and 26 patients with lung abscess were retrospectively analyzed. Reflecting the difference of pathogenesis between tuberculosis and abscess, the findings are widely different. The findings suggesting pulmonary tuberculosis rather than lung abscess were as follows; multiple and irregular necrotic areas, positive CT angiogram sign, no marginal enhancement surrounding necrosis. Contrast enhanced CT may help to distinguish pulmonary tuberculosis from lung abscess, especially in cases of caseous pneumonia showing broad consolidations or mass-like shadows. (author)

to determine whether the activity of tuberculous inflammation is associated with different clinical forms of drug-resistant pulmonary tuberculosis. The material taken from 310 patients operated on in 2010-2015 were retrospectively examined. The patients underwent economical lung resections of limited extent (typical and atypical ones of up to 3 segments) for circumscribed forms of tuberculosis with bacterial excretion. A study group consisted of 161 (51.9%) patients with drug-resistant variants of pulmonary tuberculosis. A control group included 149 (48.1%) patients with preserved susceptibility of Mycobacterium tuberculosis to anti-TB drugs. The activity of specific changes in tuberculosis was morphologically evaluated in accordance with the classification proposed by B.M. Ariel in 1998. The highest activity of fourth-to-fifth degree specific inflammation, including that outside the primary involvement focus, was obtained in the drug-resistant pulmonary tuberculosis group due to the predominance of patients with cavernous and fibrous-cavernous tuberculosis versus those in whom the susceptibility to chemotherapeutic agents was preserved. A macroscopic study showed that the primary lesion focus had a median size in one-half of the all the examinees; but large tuberculomas, caverns, and fibrous caverns over 4 cm in diameter were multiple and detected in the drug-resistant pulmonary tuberculosis group. Multidrug resistance was observed in more than 60% of the patients with fibrous-cavernous pulmonary tuberculosis, extensive drug resistance was seen in those with cavernous tuberculosis, which is an aggravating factor. The data obtained from the morphological study of the intraoperative material can specify the clinical form of tuberculosis and evaluate the efficiency of preoperative specific therapy. The highest activity of specific inflammation was observed in patients with multiple drug-resistant pulmonary tuberculosis, the prevalence of third-to-fourth degree

ABSTRACT The role of tuberculosis as a public health care priority and the availability of diagnostic tools to evaluate functional status (spirometry, plethysmography, and DLCO determination), arterial blood gases, capacity to perform exercise, lesions (chest X-ray and CT), and quality of life justify the effort to consider what needs to be done when patients have completed their treatment. To our knowledge, no review has ever evaluated this topic in a comprehensive manner. Our objective was to review the available evidence on this topic and draw conclusions regarding the future role of the "post-tuberculosis treatment" phase, which will potentially affect several million cases every year. We carried out a non-systematic literature review based on a PubMed search using specific keywords (various combinations of the terms "tuberculosis", "rehabilitation", "multidrug-resistant tuberculosis", "pulmonary disease", "obstructive lung disease", and "lung volume measurements"). The reference lists of the most important studies were retrieved in order to improve the sensitivity of the search. Manuscripts written in English, Spanish, and Russian were selected. The main areas of interest were tuberculosis sequelae following tuberculosis diagnosis and treatment; "destroyed lung"; functional evaluation of sequelae; pulmonary rehabilitation interventions (physiotherapy, long-term oxygen therapy, and ventilation); and multidrug-resistant tuberculosis.The evidence found suggests that tuberculosis is definitively responsible for functional sequelae, primarily causing an obstructive pattern on spirometry (but also restrictive and mixed patterns), and that there is a rationale for pulmonary rehabilitation. We also provide a list of variables that should be discussed in future studies on pulmonary rehabilitation in patients with post-tuberculosis sequelae. PMID:27812638

Objective: To explore the relationship between plasma adrenomedullin (AM) levels and pulmonary cancer as well as the diagnostic value of AM levels determination for differentiation of pulmonary cancer from pulmonary tuberculosis. Methods: Plasma levels of AM in patients with pulmonary cancer (n=43), pulmonary tuberculosis (n=43) and 43 controls were determined with RIA. Results: Plasma levels of AM (98.46 ± 29.28 ng/ml) in patients with pulmonary cancer were significantly higher than those in patients with pulmonary tuberculosis (61.46 ± 19.57 ng/ml) as well as those in controls (40.22 ± 8.23 ng/ml) (both P<0.01). Levels in patients with small cell carcinoma were significantly lower than those in patients with adenocarcinoma and squamous cell carcinoma (both P<0.05). Positive correlation existed between the plasma levels of AM and the severity (grading 1 to 4) of the disease (P<0.05). Conclusion: Adrenomedullin could be regarded as a valuable plasma marker for differentiating lung cancer from tuberculosis. The plasma AM levels might be able to reflect the severity and predict the prognosis of the disease. Besides, high AM levels might suggest a tentative diagnosis of lung cancer in patients without pathologic evidence. (authors)

Tuberculosis is still a considerable health problem in many countries. Rapid diagnosis of this disease is important, and adenosine deaminase (ADA) has been used as a diagnostic test. The aim of this study was to assess the diagnostic value of ADA in the sputum of patients with pulmonary tuberculosis. The current study included 40 patients with pulmonary tuberculosis (culture positive, smear ±) and 42 patients with non tuberculosis pulmonary diseases (culture negative). ADA was measured on all of the samples. The median value of ADA in non-tuberculosis patients was 2.94 (4.2) U/L and 4.01 (6.54) U/L in tuberculosis patients, but this difference was not statistically significant (p=0.100). The cut-off point of 3.1 U/L had a sensitivity of 61% and a specificity of 53%, the cut-off point of 2.81 U/L had a sensitivity of 64% and a specificity of 50% and the cut-off point of 2.78 U/L had a sensitivity of 65% and a specificity of 48%. The positive predictive values for cut-off points of 3.1, 2.81 and 2.78 U/L were 55.7%, 57.44% and 69.23%, respectively. The negative predictive values for the abovementioned cut-off points were 56.75%, 57.14% and 55.88%, respectively. Our results showed that sputum ADA test is neither specific nor sensitive. Because of its low sensitivity and specificity, determination of sputum ADA for the diagnosis of pulmonary tuberculosis is not recommended.

Between 1 January 2010 and 31 December 2016, a total of 14 U.S. and international military personnel in training at Joint Base San Antonio-Lackland, TX, were hospitalized due to suspected pulmonary tuberculosis (TB); of these, five personnel were diagnosed with active TB disease. Only one TB case had pulmonary symptoms, but these symptoms were not suggestive of TB. The incidence rate in the training population was 1.89 per 100,000 population (95% CI: 0.81, 4.42), with a higher rate when restricted to international military students attending the Defense Language Institute English Language Center. No instances of TB transmission were identified. The variety of atypical presentations and their resulting diagnostic and public health challenges prompted this retrospective review of all hospitalized cases. This case series highlights both the importance of a high index of clinical suspicion when TB is being considered in close congregate settings as well as the risk of overreliance on acid-fast bacilli staining and nucleic acid amplification testing for ruling out active pulmonary disease in young, otherwise healthy trainees. Practical solutions are suggested.

The use of radiopharmaceuticals in evaluation of pulmonary tuberculosis may help to resolve difficult diagnostic problems such as discordance between sputum examinations and chest roentgenographic findings. We investigated the usefulness of 99m Tc-methoxyisobutylisonitrile (MIBI) scintigraphy in the detection of active pulmonary tuberculosis. Forty-six patients with suspected active pulmonary tuberculosis were studied with sputum smear of AFB, sputum AFB culture, chest X-ray and MIBI scan. MIBI image was obtained 15 and 60 min after intravenous injection of 370MBq(10mCi) 99m Tc-MIBI. In 16 patients of them Ga scans were performed in addition to MIBI scan. Repeated MIBI scans were done in 7 patients with active pulmonary tuberculosis after 4∼6 months of antituberculous chemotherapy. Thirty-two patients were confirmed as active tuberculosis by sputum culture. Sensitivity of MIBI scan to active tuberculosis was 87.5%(28/32) and MIBI findings were negative in all of 14 patients with inactive disease. Focal uptake of MIBI was dense in the area that was strongly suggested active tuberculous lesions by chest roentgenogram. There was no discordance between MIBI and Ga image in 16 patients. But the uptake areas of Ga images were broader than that of MIBI images. After 4∼6 months of antituberculous treatment all repeated MIBI scans revealed negative findings except 1 patient with persistent active pulmonary tuberculosis due to drug resistance. MIBI scan could be used in the detection of active pulmonary tuberculosis as a useful noninvasive diagnostic tool

Full Text Available BACKGROUND: Susceptibility to tuberculosis is not only determined by Mycobacterium tuberculosis infection, but also by the genetic component of the host. Macrophage receptor with a collagenous structure (MARCO is essential components required for toll like receptor-signaling in macrophage response to Mycobacterium tuberculosis, which may contribute to tuberculosis risk. PRINCIPAL FINDINGS: To specifically investigated whether single nucleotide polymorphisms (SNPs in MARCO gene are associated with pulmonary tuberculosis in Chinese Han population. By selecting tagging SNPs in MARCO gene, 17 tag SNPs were identified and genotyped in 923 pulmonary tuberculosis patients and 1033 healthy control subjects using a hospital based case-control association study. Single-point and haplotype analysis revealed an association in intron and exon region of MARCO gene. One SNP (rs17009726 was associated with susceptibility to pulmonary tuberculosis, where the carriers of the G allele had a 1.65 fold (95% CI = 1.32-2.05, p(corrected = 9.27E-5 increased risk of pulmonary tuberculosis. Haplotype analysis revealed that haplotype GC containing G allele of 17009726 and haplotype TGCC (rs17795618T/A, rs1371562G/T, rs6761637T/C, rs2011839C/T were also associated with susceptibility to pulmonary tuberculosis (p(corrected = 0.0001 and 0.029, respectively. CONCLUSIONS: Our study suggested that genetic variants in MARCO gene were associated with pulmonary tuberculosis susceptibility in Chinese Han population, and the findings emphasize the importance of MARCO mediated immune responses in the pathogenesis of tuberculosis.

Objective: To determine the resistance patterns of mycobacterium tuberculosis (MTB) isolates among category I and II patients of pulmonary tuberculosis. Methods: This cross sectional study was conducted at the Department of Medicine, Liaquat University of Medical and Health Sciences Jamshoro, from November 2008 to September 2009. Patients were divided into category I and II. The sputa were collected, stained with Ziehl-Nielsen (Z-N) staining and ultimately inoculated on Lowenstein-Jensen (L-J) media for six weeks. Out of 890 pulmonary tuberculosis (PTB) patients, the growth was obtained in 285 cases. The Drug sensitivity testing (DST) for Isoniazid (INH), Rifampicin (RIF), Ethambutol (EMB) Pyrazinamide (PZA) and Streptomycin (SM) were performed. The data was analyzed on SPSS 10.0. A p-value of <0.05 was taken as significant. Result: Out of 285 cases, 176 (61.75%) were male and 109 (38.24%) female. The mean age was 37 +- 19.90 years. The DST showed drug sensitive and drug resistant isolates in 80 (28.05%) and 205 (71.92%) cases respectively (p=0.001). The drug resistant tuberculosis (DR-TB) rates for individual drugs; INH, RIF, EMB, PZA and SM were 51,22%, 15.4%, 13.33%, 9%12, and 3.85% respectively (p=0.03). The MDR-TB isolates were detected in 120 (42.10%) cases, including 5 (5.88%) in category I and 115 (57.50%) in category II patients (p=0.0001). Conclusion: Drug resistant and multidrug resistant tuberculosis was observed mainly in category II patients. However, primary MDR was also observed in category I patients and reflects dissemination of MDR cases within the community. (author)

Objective: To study the serum HA and LN level in patients with pulmonary tuberculosis and their response to therapy. Methods: Serum HA and LN levels were measured with RIA in: (1) 42 patients with active pulmonary tuberculosis both before and after 2 months' therapy, (2) 40 patients with non-active pulmonary TB and 330 controls. Results: The serum HA and LN level in patients with active pulmonary tubemulosis were significantly higher than those in controls (P < 0.01 ), while no significant difference could Be found Between the levels in patients with non-active pulmonary tuberculosis and controls. The serum HA and LN level in patients with active pulmonary tuberculosis dropped after therapy, but were still higher than those in controls. Significant correlation could Be found between HA and LN levels (P<0.01). The HA and LN levels were positively correlated with severity of the disease, ESR and CRP contents. Conclusion: The measurement of serum HA and LN is valuable for early diagnosis, monitoring development and assessment of therapeutic effect in patients with pulmonary tubemulosis. (authors)

Multidrug resistant tuberculosis (MDR-TB) poses problems in treatment, costs and treatment outcomes. It is not known if classically described risk factors for MDR-TB in other countries are the same in Mexico and the frequency of the association between diabetes mellitus (DM) and MDR-TB in our country is not clear. We undertook this study to analyze risk factors associated with the development of MDR-TB, with emphasis on DM. A case-control study in the state of San Luis Potosi (SLP), Mexico was carried out. All pulmonary MDR-TB patients diagnosed in the state of SLP between 1998 and 2013 (36 cases) evaluated at a state pharmacoresistant tuberculosis (TB) clinic and committee; 139 controls were randomly selected from all pulmonary non-multidrug-resistant tuberculosis (non-MDR-TB) cases identified between 2003 and 2008. Cases and controls were diagnosed and treated under programmatic conditions. Age, gender, malnutrition, being a health-care worker, HIV/AIDS status, and drug abuse were not significantly different between MDR-TB and non-MDR-TB patients. Significant differences between MDR-TB and non-MDR-TB patients were DM (47.2 vs. 28.1%; p = 0.028); previous anti-TB treatments (3 vs. 0, respectively; p <0.001), and duration of first anti-TB treatment (8 vs. 6 months, respectively; p <0.001). MDR-TB and DM are associated in 47.2% of MDR TB cases (17/36) in this study. Other recognized factors were not found to be significantly different in MDR-TB compared to non-MDR-TB in this study. Cost-feasible strategies must be implemented in the treatment of DM-TB in order to prevent the selection of MDR-TB. Copyright © 2015 IMSS. Published by Elsevier Inc. All rights reserved.

By means of radiocardiography and radiometry central hemodynamic parameters were measured, using 131 I-labelled human serum albumin, pulmonary-artery systolic pressure (PASP) was assessed indirectly, and serum complement and circulating immune complexes (CIC) were measured before 48 hours after subcutaneous administration of 20 TU tuberculin in 65 patients with active pulmonary tuberculosis, 25 clinically-cured tuberculosis patients and 16 patients with chronic nonspecific pulmonary diseases (CNPD). A potent direct correlation was demonstrated between the CIC level and PASP elevation. It is suggested that close correlation between CIC and PASP elevation may be evidence of their pathogenetic involvement in chronic pulmonary heart, as well as the fact that prolonged and effective chemotherapy weakens adverse cardiovascular effects of immunologic factors, which can however persist in some individuals even after they are apparently cured from tuberculosis

The purpose of this paper was to investigate the clinical and radiological features of pulmonary tuberculosis presenting as interstitial lung diseases (ILD). We analyzed the data of cases suspected of diffuse parenchyma lung diseases at this hospital between October 2003 and October 2007. The diagnosis of active pulmonary tuberculosis was based on epithelioid granuloma or positive acid-fast bacilli in lung biopsy and changes on serial radiographs obtained during treatment. The data of a series of 230 consecutive patients with suspected ILD were retrospectively analyzed. The diagnosis was confirmed by lung biopsy. Twelve patients were confirmed to have pulmonary tuberculosis. There were 5 males and 7 females with a mean age of 38 +/- 11 years (range, 17 - 68). The median course of disease in these patients was 3 months (range, 0.5 - 18 months). Patients with pulmonary tuberculosis presented with fever (11/12), cough (9/12), weight loss (7/12), dyspnea (7/12), lymphadenopathy (4/12), and splenohepatomegaly (2/12). On chest CT scan, ground-glass attenuation was identified in 4, bilateral patchy infiltration in 5, tree-in-bud appearance 1, and centrilobular lesions in 2 of the 12 patients. During the follow-up period (median, 9 month, range from 3 to 12 month), 11 patients improved, but 1 died of diabetic ketoacidosis. The diagnosis of pulmonary tuberculosis should be considered in suspected ILD patients presenting with fever, splenohepatomegaly and lymphadenopathy.

To explore the expression of high mobility group box-1 (HMGB1) in the lung tissue and serum of patients with pulmonary tuberculosis and to explore its relationship with tumor necrosis factor (TNF)-α and interleukin(IL)-1β. Sixty samples of lung tissues were obtained from patients with pulmonary tuberculosis who had underwent pneumonectomy in Department of Chest Surgery, First Affiliated Hospital of Zunyi Medical College from June 2010 to December 2011. At the same period, 40 normal lung samples were also obtained from patients with pulmonary contusion and lung cancer by surgical resections as the control group. The mRNA expressions of HMGB1 was detected by reverse transcription-polymerase chain reaction (RT-PCR), and the protein level of HMGB1 was measured by immunohistochemical staining of tissue microarrays in lung tissue. Blood samples were taken from 89 patients with active pulmonary tuberculosis (pulmonary tuberculosis group), including hematogenous disseminated pulmonary tuberculosis (type II) in 35 cases and secondary pulmonary tuberculosis (type III) in 54 cases, and 50 healthy volunteers (control group). Furthermore, the 54 patients with secondary pulmonary tuberculosis were divided into different subgroups according to cavity formation and the lung fields involved: patients without lung cavity (35 cases) vs those with lung cavity (19 cases), patients with involvement of pulmonary tuberculosis (69 ± 29) was significantly higher than that in normal lung tissue (22 ± 12) (t = 2.389, P pulmonary tuberculosis (786 ± 86) was significantly higher than that in normal lung tissue (202 ± 60) (t = 3.872, P pulmonary tuberculosis group were (5.0 ± 3.2) µg/L, (118 ± 77) ng/L and (33 ± 20) ng/L, respectively, which were significantly higher than those in the control group [(1.7 ± 1.0) µg/L, (40 ± 11) ng/L and (18 ± 12) ng/L, respectively], the respective t values being -0.928, 4.268 and 11.064, all P pulmonary tuberculosis, the serum concentration of HMGB

Pulmonary Mycobacterium tuberculosis (Beijing strain infection in a stray dog : clinical communication

2008-05-01

Full Text Available Mycobacterium tuberculosis infection in dogs is rarely reported and has not previously been documented in South Africa. A case of a stray Maltese crossbreed dog with extensive multifocal pulmonary tuberculosis due to M. tuberculosis is described. Pulmonary granulomas in this case were poorly encapsulated and contained large numbers of acid-fast bacteria, highlighting the potential for infected companion animals to excrete the pathogen. Treatment of canine tuberculosis is generally not advised, and for this reason, euthanasia of diseased animals must be advocated in most instances. Physicians and veterinarians must be aware that companion animals with active disease caused by M. tuberculosis could act as a potential source of infection.

2004-01-01

Whether the main points of treatment for bronchial obstructive syndrome (BOS) in chronic obstructive lung disease (COLD) can be adapted for patients with pulmonary tuberculosis (PT) was studied. For this purpose, 435 patients with PT with signs of BOS (forced expiratory volume at 1 second (FEV1) 70% of the normal values; 2) 229 patients with FEV1 69-50%; 3) 102 patients with FEV1 bronchial obstructive syndrome in patients with pulmonary tuberculosis was highly effective, promotes the amelioration of the degree of respiratory symptoms in patients with IPT by 2 to 8 times, in those with FCPT by more than 2-3 times, and in those with PS by 1.45-10 times. The differences in the efficiency of bronchodilator therapy depend on the baseline level of bronchial obstruction. In patients with pulmonary tuberculosis concurrent with BO, the use of current inhalation bronchodilator therapy results in a substantial increase in FEV1, which differentiates BOS in PT from COLD. The use of the proposed therapy in the multimodality treatment of patients with pulmonary tuberculosis showed no statistically significant differences in the changes in the degree of X-ray symptoms while this therapy permits acceleration of abacillation in patients with IPT by 16.8% and in those with FCPT by 14.8%. Effective bronchodilator therapy considerably enhances life quality in patients. Thus, early systematic and long-term performance of the bronchodilator therapy, based on the principles of bronchodilator therapy for COLD, in patients with PT concurrent with BOS may substantially enhance the efficiency of treatment in this category of patients.

Full Text Available BACKGROUND Diabetes mellitus has been reported to modify the presenting features of pulmonary tuberculosis. In recent decades, with the increasing prevalence of tuberculosis in diabetes mellitus cases in the world, the relationship is re-emerging as a significant public health problem. Improved understanding of the bidirectional relationship of the two diseases is necessary for proper planning and collaboration to reduce the dual burden of diabetes and TB. MATERIALS AND METHODS The study was conducted at Thanjavur Medical College Hospital during the time period January 2017 to August 2017. It is a prospective study. 60 cases of diabetes mellitus with pulmonary tuberculosis were studied. Their clinical profile and chest radiograph results were analysed. RESULTS The predominant clinical symptoms noted were anorexia (82%, cough (80% and fever (60%. 56% of male patients were smokers. Average duration of diabetes was 68 years. The average fasting and postprandial blood sugar values in the study group was 238.5 and 340.0 mg/dL, respectively. 100% of the patients were sputum positive for AFB. Out of these, 45% of cases were high sputum positivity (3+. Cavitatory lesions (52% were the most common type of lesion noted in both age group patients followed by fibrosis (33% and infiltration (25%. Lower lung field involvement was noted in 32% of patients and was more common in patients greater than 40 years. CONCLUSION Severe hyperglycaemia appears to be a contributory factor to the development of pulmonary tuberculosis in diabetics. This has potentially serious implications for tuberculosis control and it must become a priority to initiate focused and coordinated action like case finding, treatment of latent tuberculosis and efforts to diagnose, detect and treat DM may have a beneficial impact on TB control.

A retrospective cross-sectional study involving a record review of national TB and laboratory registers. Of 2420 TB cases identified, 709 (29%) were registered as smear-negative pulmonary TB. Of the 695 (98%) with information on smear examination, 222 (32%) had no smear recorded, 61 (9%) had one smear, 86 (12%) two smears and 326 (47%) three smears. Among the 473 patients who had at least one smear, 238 (50%) were registered before sputum examination, 131 (28%) within 1 week, 72 (15%) between 1 and 4 weeks, and 34 (7%) >4 weeks after sputum examination. NTPs in Kiribati and the Marshall Islands are diagnosing 29% of all TB patients as smear-negative pulmonary TB. Many patients do not have smears done or are registered before undergoing smear examination. Corrective measures are needed.

Technetium-99m MIBI was developed as a myocardiac perfusion imagine agent and has been used effectively in the detection and post-therapeutic evaluation of various neoplasm such as thyroid, lung, bone and breast tumors. As an infrequent findings, Tc-99m MIBI agent has shown in non-neoplastic pulmonary conditions including fibroding alveolitis, pulmonary actinomycosis, active pulmonary sarcoidosis, pulmonary interstitial fibrosis in progressive systemic sclerosis and active osteomyelitis. In a recent report conducted by Cetin Oncel, Tc-99m MIBI imaging is an effective method in the detection and follow-up of pulmonary tuberculosis. We have also experienced Tc-99m-MIBI uptake in active pulmonary tuberculosis incidentally found in a patient with suspected proliferative villonodular synovitis of the left ankle.

Full Text Available Introduction: Pulmonary fungus ball is a rare complication in pre-existing pulmonary cavitary lesions, due to some chronic pulmonary diseases including tuberculosis, lung abscess and sarcoidosis. Fungus ball is mostly caused by aspergillus. In many patients, fungus ball is asymptomatic, but in a significant number of them it can develop cough and hemoptysis, which may be massive and fatal. The cornerstone of assessment is chest imaging, along with sputum culture or aspergillus antibody in patient's serum. The purpose of this report is increment in attention to this complication in patients with previous pulmonary tuberculosis (TB. Case Presentation: The patient was a 23-year-old woman with chief complaint of fever, cough and hemoptysis, who was hospitalized in the Infectious Diseases Ward of Farshchian Sina hospital in March 2016. She had a history of anti-TB therapy from two years before. Sputum and bronchoalveolar lavage (BAL were negative for cytology and Mycobacterium tuberculosis, but cultures of both samples were positive for Aspergillus niger. Her lung contrast-enhanced computerized tomography (CECT scan revealed the presence of a fungus ball inside the upper lobe cavity of right lung. After lobectomy, fungal mass was confirmed by histopathology. Conclusions: In patients with pulmonary complaints (especially hemoptysis and history of cavitary pulmonary tuberculosis, the differential diagnosis of community-acquired pneumonia, lung abscess, reactivation of tuberculosis and lung cancer as well as fungal infections should be considered.

Objective: To study the CT characteristics of coexisting pulmonary tuberculosis and lung cancer. Methods: One hundred and four patients of coexisting pulmonary tuberculosis and lung cancer proved by histology, cytology or clinical underwent CT examination. All patients were divided into two groups, group Ⅰ were the patients with the lung cancer after tuberculosis or both found simultaneously (group Ⅰ a with peripheral lung cancer and group Ⅰ b with central lung cancer), group Ⅱ with tuberculosis during lung cancer chemotherapy (group Ⅱ a with peripheral lung cancer and group Ⅱ b with central lung cancer). Imaging characteristics of tuberculosis and lung cancer were compared. χ"2 test and t test were used for the statistical analysis. Results: Of 104 patients, there were 92 patients (88.5%) in group Ⅰ and 12 patients (11.5%) in group Ⅱ. Seventy patients (76.1%) of lung cancer and tuberculosis were located in the same lobe and 22 patients (23.9%) in the different lobes in group Ⅰ. There was no significant difference in distribution of tuberculosis between group Ⅰ and group Ⅱ (χ"2 = 4.302, P = 0.507). The fibrous stripes, nodules of calcification and pleural adhesion of tuberculosis were statistically significant between the two groups (χ"2 = 22.737, 15.193, 27.792, P < 0.05). There were 33 central lung cancers and 71 peripheral lung cancers. In group Ⅰ a (64 patients of peripheral lung cancers), 39 patients (60.9%) had typical manifestations and most of the lesions were ≥ 3 cm (n = 49, 76.6%), solid lesions showed variable enhancement. Conclusions: Secondary tuberculosis during lung cancer chemotherapy has the same CT characteristics with the common active tuberculosis. The morphology, enhancement pattern of lesion and follow-up are helpful for the diagnosis of lung cancer after tuberculosis. (authors)

Objective: To investigate CT characteristics of pulmonary tuberculosis by analyzing the reasons of misdiagnosis in 35 patients with pulmonary tuberculosis. Methods: The patients in this study included 19 men and 16 women, with ages ranging from 18 to 79 years old. Chest CT scans were performed in all patients. The CT films were reviewed retrospectively by two senior radiologists and were correlated with pathologic findings. The misdiagnosing reasons were analyzed. Results: Misdiagnoses as lung cancer were made in 29 cases, pneumonia in 4 cases, and other diseases in 2 cases. The lesions on CT films appeared as nodules and masses in 14 cases, pulmonary segmental and lobar shadows in 19 cases, and hilar and mediastinal masses in 2 cases. Conclusion: The main causes of misdiagnosis for pulmonary tuberculosis are atypical radiological appearance on CT films, inadequate visualized lesions, and lacking of combination of CT findings with that of chest radiography

Full Text Available Abstract Background The prevalence of pulmonary tuberculosis among college students in Shaanxi is high. Although tuberculosis leaves much psychological and social impact on patients, little is known about its impact on college students. The objective of this study is to explore the experiences and psychological process of college students with pulmonary tuberculosis in Shaanxi, China. Methods 17 college students with pulmonary tuberculosis were recruited purposively from 9 colleges in Shaanxi. In-depth interviews were conducted to collect data and a thematic framework analysis was used. Results The participants reported that pulmonary tuberculosis deeply influenced their mental health. They were fearful to the nature of pulmonary tuberculosis at the stage of diagnosis, anxious about the illness before the period of diagnosis and the early week of the treatment, excessive worry immediately before the first recheck. They expected an early full recovery, bored on tedious treatment life and worried about future heath and prospects during the whole treatment phase. Their daily life was also influenced, namely discontinued studies, isolation and increased financial burden. They also reported that they could get strong supports from family members, while little supports from healthcare workers and their friends. Conclusions The participants' psychological pressure was significant during the treatment. In addition, there was serious conflict between treatment and study; social support provided for them was insufficient. Healthcare workers should provide psychological support for college students with pulmonary tuberculosis according to the psychological characteristics and offer social support through strengthening communication with them. Colleges should follow governmental policies on TB exactly and provide opportunities for the patients to continue their studies.

The radiological patterns of culture-proven pulmonary tuberculosis in 154 children under the age of 14 years were studied. Good quality radiographs were an essential requirement to the study, and in cases where lymphadenopathy was in doubt, tomograms or high kV magnification films were obtained. The radiographical terms used were defined and the results of film review were analysed to show the prevalent patterns. These are summarized at the end of the article. It is felt that awareness of the radiographic patterns in paediatric pulmonary tuberculosis will be of value of those working in communities where tuberculosis is unusual or rare, in immigrant communities, and also for the investigation of children who are inadvertently exposed to the disease.

The cells T CD4+ T and CD8+ can be subdivided into phenotypes naïve, T of central memory, T of effector memory and effector, according to the expression of surface molecules CD45RO and CD27. The T lymphocytes are cells of long life with capacity of rapid expansion and function, after a new antigenic exposure. In tuberculosis, it was found that specific memory T cells are present, however, gaps remain about the role of such cells in the disease immunology. In this study, the phenotypic profile was analyzed and characterized the functionality of CD4+ T lymphocytes and CD8+ T cells of memory and effector, in response to specific stimuli in vitro, in patients with active pulmonary TB, compared to individuals with latent infection with Mycobacterium tuberculosis the ones treated with pulmonary TB. It was observed that the group of patients with active pulmonary tuberculosis was the one which presented the highest proportion of cells T CD4+ of central memory IFN-ɣ+ e TNF-α+, suggesting that in TB, these T of central memory cells would have a profile of protective response, being an important target of study for the development of more effective vaccines; this group also developed lower proportion of CD8+ T effector lymphocytes than the others, a probable cause of specific and less effective response against the bacillus in these individuals; the ones treated for pulmonary tuberculosis were those who developed higher proportion of T CD4+ of memory central IL-17+ cells, indicating that the stimulation of long duration, with high antigenic load, followed by elimination of the pathogen, contribute to more significant generation of such cells; individuals with latent infection by M. tuberculosis and treated for pulmonary tuberculosis, showed greater response of CD8+ T effector lymphocytes IFN-ɣ+ than the controls, suggesting that these cells, as well as CD4+ T lymphocytes, have crucial role of protection against M. tuberculosis. These findings have contributed to a better

Most cases of adult-onset tuberculosis (TB) result from reactivation of a pre-existing Mycobacterium tuberculosis infection. Mycobacterium tuberculosis usually invades the respiratory tract and most patients develop intrapulmonary TB; however, some patients develop concurrent pulmonary and extra-pulmonary TB. The purpose of the present study was to identify the demographic and clinical factors associated with an increased risk of concurrent extra-pulmonary diseases in patients with pulmonary TB. We compared patients who had isolated pulmonary TB with patients who had concurrent pulmonary and extra-pulmonary TB. We initially analyzed one-million randomly selected subjects from the population-based Taiwan National Health Insurance database. Based on analysis of 5414 pulmonary TB patients in this database, women were more likely than men to have concurrent extra-pulmonary TB (OR: 1.30, p = 0.013). A separate analysis of the Kaohsiung Medical University Hospital database, which relied on sputum culture-proven pulmonary TB, indicated that women were more likely than men to have concurrent extra-pulmonary TB (OR: 1.62, p = 0.039). There was no significant gender difference in extra-pulmonary TB for patients younger than 45 years in either database. However, for patients 45 years and older, women were more likely than men to have concurrent extra-pulmonary TB (insurance database: 9.0% vs. 6.8%, p = 0.016, OR: 1.36; hospital database: 27.3% vs. 16.0%, p = 0.008, OR = 1.98). Our results indicate that among patients who have pulmonary TB, older females have an increased risk for concurrent extra-pulmonary TB.

Full Text Available BACKGROUND: From long instances, it is debatable whether three sputum specimens are required for the diagnosis of pulmonary tuberculosis (TB or TB can be diagnosed effectively using two consecutive sputum specimens. This study was set out to evaluate the significance of examining multiple sputum specimens in diagnosis of TB. METHODS: We retrospectively reviewed the acid-fast bacillus (AFB smear and culture results of three consecutive days' sputum specimens from 413 confirmed TB patients which were detected as part of a larger active case finding study in Dhaka Central Jail, the largest correctional facility in Bangladesh. RESULTS: AFB was detected from 81% (n = 334 patients, of which 89% (n = 297 were diagnosed from the first and additional 9% (n = 30 were from the second sputum specimen. M. tuberculosis growth was observed for 406 patients and 85% (n = 343 were obtained from the first sputum and additional 10% (n = 42 were from the second one. The third specimen didn't show significant additional diagnostic value for the detection of AFB by microscopy or growth of the M. tuberculosis. CONCLUSIONS: We concluded from our study results that examining two consecutive sputum specimens is sufficient enough for the effective diagnosis of TB. It can also decrease the laboratory workload and hence improve the quality of work in settings with high TB burden like Bangladesh.

To evaluate the utility of high-resolution computed tomography (HRCT), as used to determine the activity of tuberculosis, and to analyze the HRCT findings in active and in inactive tuberculosis. We analyzed the HRCT findings of 100 patients (54 men, 46 women; average age, 54 years) who according to the results of chest radiography had pulmonary tuberculosis of undetermined activity. We assessed HRCT findings such as the presence of a centrilobular, macro-, or micronodule; consolidation, ground-glass opacity, cavity, interlobular septal thickening, irregular linear opacities, bronchial wall thickening, bronchovascular bundle distortion, bronchiectasis, atelectasis, and pericicatrical emphysema. We compared the ratio of the area of nodule and consolidation to that of whole lung, and compared the findings between active and inactive tuberculosis. Eleven of 100 patients were excluded because the final diagnosis was other than tuberculosis. In 59 patients, the presence of active pulmonary tuberculosis was proven by positive sputum smear and/or culture for mycobacterium tuberculosis. On the basis of the negative results of these tests, pulmonary tuberculosis was found to be inactive in 30 patients; serial chest radiographs indicated that their condition remained stable over a 6-month period. For HRCT, sensitivity was 96.6%, specificity 56.7%, positive predictive value 81.4%, negative predictive value 89.5%, and accuracy 83.1%. For active tuberculosis, the presence of centrilobular nodules, tree-in-bud, macronodules, cavity within the nodule, and consolidations was statistically significant, while for inactive tuberculosis, that of irregular linear opacities, micronodules, bronchiectasis, and cicatrization atectasis was similarly significant. The CT score for the area of nodules and consolidations was higher in active than in inactive tuberculosis, but only the nodule score showed statistical significance. HRCT can be a useful diagnostic tool for evaluating the activity

Full Text Available Spontaneous bronchoesophageal fistula in the adult is a rare clinical entity. Most bronchoesophageal fistulae are due to malignancy, prolonged endotracheal intubation or trauma. Granulomatous infections like tuberculosis, HIV and mediastinitis are rare causes of acquired bronchoesophageal fistula. We report a case of a 50 year old man, treated for pulmonary tuberculosis 15 years ago, who developed a spontaneous bronchoesophageal fistula between the mid-esophagus and right main stem bronchus, having no history of malignancy or trauma. Surgical closure of the fistula was done and post operative recovery was uneventful. In this case, the bronchoesophageal fistula probably developed as a delayed sequela of pulmonary tuberculosis as the patient had no active signs of pulmonary tuberculosis clinically or histopathologically.

Full Text Available In the past, anaerobes were the most common cause of community-acquired lung abscess; Streptococcus species were the second most common cause. In recent years, this has changed. Klebsiella pneumoniae is now most common cause of community- acquired lung abscess, although Streptococcus species remain pathogen of major importance. We present two cases of pulmonary cavitation due to Streptococcus pneumoniae which resembled pulmonary tuberculosis with regards to their history and radiological findings. These are examples of a common diagnosis presenting in an uncommon way. Our cases had some peculiarities: they had a clinical picture strongly suggestive of pulmonary tuberculosis or lung cancer rather than necrotizing infectious pneumonia in patients with no comorbidities or underlying diseases (including oral or dental pathologies. Radiological findings did not help the clinicians: pulmonary tuberculosis was the first diagnostic hypothesis in both cases. An underlying lung cancer was excluded in the first case only after invasive pulmonary procedures.

Vital capacity (VC), forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), FEV1/VC%, PEF, MEF25, MEF50, MEF75, TLC, TGV, pulmonary residual volume (PRV), Raw, Rin, Rcx, DLCO-SB, DLCO-SS/VA, PaO2, and PaCO2 were determined in 40 patients with focal pulmonary tuberculosis. Changes were found in lung volumes and capacities in 75%, impaired bronchial patency and pulmonary gas exchange dysfunction were in 57.5 and 25%, respectively. The lung volume and capacity changes appeared mainly as increased TGV and PRV; impaired bronchial patency presented as decreased MEF50, MEF75, and FEV1/VC%; pulmonary gas exchange dysfunction manifested itself as reduced DLCO-SB, PaO2, and PaCO2. The magnitude of the observed functional changes was generally slight. TGV and PRL increased up to 148-187 and 142-223% of the normal values, respectively; MEF50, MEF75, FEV1/VC%, and DLCO decreased to 59-24, 58-26, 78-57, and 78-67% of the normal values and PaO2 and PaCO2 did to 79-69 and 34-30 cm Hg.

Full Text Available Tuberculosis infection may remain latent, but the disease is nevertheless a serious public health issue. Various epidemiological studies on pulmonary tuberculosis have considered the spatial component and taken it into account, revealing the tendency of this disease to cluster in particular locations. The aim was to assess the contribution of Knowledge Attitude and Practice (KAP to the distribution of tuberculosis and to provide information for the improvement of the National Tuberculosis Program.We investigated the role of KAP to distribution patterns of pulmonary tuberculosis in Antananarivo. First, we performed spatial scanning of tuberculosis aggregation among permanent cases resident in Antananarivo Urban Township using the Kulldorff method, and then we carried out a quantitative study on KAP, involving TB patients. The KAP study in the population was based on qualitative methods with focus groups.The disease still clusters in the same districts identified in the previous study. The principal cluster covered 22 neighborhoods. Most of them are part of the first district. A secondary cluster was found, involving 18 neighborhoods in the sixth district and two neighborhoods in the fifth. The relative risk was respectively 1.7 (p<10-6 in the principal cluster and 1.6 (p<10-3 in the secondary cluster. Our study showed that more was known about TB symptoms than about the duration of the disease or free treatment. Knowledge about TB was limited to that acquired at school or from relatives with TB. The attitude and practices of patients and the population in general indicated that there is still a stigma attached to tuberculosis.This type of survey can be conducted in remote zones where the tuberculosis-related KAP of the TB patients and the general population is less known or not documented; the findings could be used to adapt control measures to the local particularities.

To evaluate the prevalence of pulmonary function abnormalities and to investigate the factors affecting lung function in patients treated for pulmonary tuberculosis. A total of 214 consecutive patients (132 men and 82 women; 20-82 years of age), treated for pulmonary tuberculosis and followed at a local dispensary, underwent spirometry and plethysmography at least one year after treatment. Pulmonary impairment was present in 102 (47.7%) of the 214 patients evaluated. The most common functional alteration was obstructive lung disease (seen in 34.6%). Of the 214 patients, 60 (28.0%) showed reduced pulmonary function (FEV1 below the lower limit of normal). Risk factors for reduced pulmonary function were having had culture-positive pulmonary tuberculosis in the past, being over 50 years of age, having recurrent tuberculosis, and having a lower level of education. Nearly half of all tuberculosis patients evolve to impaired pulmonary function. That underscores the need for pulmonary function testing after the end of treatment. Avaliar a prevalência de alterações da função pulmonar e investigar os fatores que afetam a função pulmonar em pacientes tratados para tuberculose pulmonar. Um total de 214 pacientes consecutivos (132 homens e 82 mulheres; 20-82 anos de idade), tratados para tuberculose pulmonar e acompanhados em um dispensário local, foi submetido a espirometria e pletismografia pelo menos um ano após o tratamento. O comprometimento pulmonar estava presente em 102 (47,7%) dos 214 pacientes avaliados. A alteração funcional mais comum foi o distúrbio ventilatório obstrutivo (observado em 34,6%). Dos 214 pacientes, 60 (28,0%) apresentaram função pulmonar reduzida (VEF1 abaixo do limite inferior de normalidade). Os fatores de risco para função pulmonar reduzida foram tuberculose pulmonar com cultura positiva no passado, idade acima de 50 anos, recidiva de tuberculose e menor nível de escolaridade. Quase metade de todos os pacientes com tuberculose

Background Tuberculosis (TB) remains a public health problem in Mexico while the incidence of diabetes mellitus type 2 (DM) has increased rapidly in recent years. Objective To describe the trends of incidence rates of pulmonary TB associated with DM and not associated with DM and to compare the results of treatment outcomes in patients with and without DM. Materials and Methods We analysed the National Tuberculosis Registry from 2000 to 2012 including patients with pulmonary TB among individuals older than 20 years of age. The association between DM and treatment failure was analysed using logistic regression, accounting for clustering due to regional distribution. Results In Mexico from 2000 to 2012, the incidence rates of pulmonary TB associated to DM increased by 82.64%, (p pulmonary TB rate without DM, which decreased by 26.77%, (p pulmonary TB. In addition, patients who suffer from both diseases have a greater probability of treatment failure. PMID:26075393

A 62-year-old man presented in June 2006 with right thoracic pain, cough, and weight loss, which had persisted for 3 months. Chest X-ray showed a mass-like shadow in the right pulmonary apex, suggesting a stage IIIb adenocarcinoma which was confirmed by biopsy. We gave a total radiation dose of 60 Gy, after this which general malaise and weakness were noted. The results of endocrinological examinations suggested syndrome of inappropriate antidiuretic hormone secretion (SIADH). Thoracic CT showed ground-glass opacity (GGO) in both lungs, and we could not rule out pulmonary tuberculosis. A sputum was positive for acid-fast stain and polymerase polymerase chain reaction-Tuberculosa (PCR-Tb), suggesting that SIADH was associated with pulmonary tuberculosis. Water restriction, i.v. physiological saline, and anti-tuberculosis therapy relieved hyponatremia and the symptoms. (author)

Full Text Available Aims: Leptin is one of the most important fat-derived hormones. Several studies have shown that serum leptin levels in systemic inflammatory diseases are reduced. The aim of this study was to evaluate the serum leptin levels in three groups: patients with active pulmonary tuberculosis (TB, patients with non-pulmonary infections (acute pneumonia and normal people. Materials & Methods: In this cross-sectional study, in 2010, 40 patients with active pulmonary TB (case group and 40 patients with non-pulmonary infections (positive control group admitted to Boo-Ali hospital in Zahedan and 40 healthy subjects (negative control group were selected using easy access and serum leptin levels were evaluated by ELISA. Data were analyzed by SPSS 18 software and one-way ANOVA. Findings: The mean of serum leptin levels in patients with non-pulmonary infections (p=0.030 and in patients with active pulmonary TB (p=0.004 were significantly lower than normal group, but the mean of serum leptin levels in patients with active pulmonary TB and patients with non-pulmonary infections were not significantly different (p=0.555. Conclusion: Serum leptin levels are lower in patients with active pulmonary tuberculosis and in patients with non-pulmonary infections than in normal people, but there is no difference between patients with active pulmonary tuberculosis and patients with non-pulmonary infections. Therefore, serum leptin levels are not an appropriate marker for the differentiation of active pulmonary tuberculosis from pulmonary infections (acute pneumonia.

The case of post TB is a problem that arises in the community. Pulmonary tuberculosis (TB) can affect lung function. Therefore, we evaluated impaired pulmonary function in subjects with diagnosed prior pulmonary TB. A Case Series study, pulmonary function test was performed in subjects with a history of pulmonary tuberculosis; aged ≥18 years were included. Exclusion criteria was a subject who had asthma, obesity, abnormal thorax and smoking history. We measured FEV1 and FVC to evaluate pulmonary function. Airflow obstruction was FEV1/FVC%pulmonary TB, 5 subjects (23%) had airflow obstruction with FEV1/FVC% value pulmonary TB.

Full Text Available Genital tuberculosis is an important under-diagnosed factor of infertility. A vast majority of cases are asymptomatic and diagnosing them will help in treating such patients. We conducted a retrospective study in a tertiary care hospital of Delhi with an aim to compare different methods i.e., histopathological examination (HPE, acid-fast bacilli (AFB smears, Lowenstein-Jensen (LJ culture, BACTEC culture and polymerase chain reaction deoxyribonucleic acid (PCR-DNA for diagnosing endometrial tuberculosis in infertile women. The data from 546 samples of endometrial biopsy histopathology, AFB smears and LJ culture was collected and then analyzed. Of these, HPE for tuberculosis was positive in 13, LJ culture in 10, AFB smear was positive in one case. BACTEC and PCR-DNA were feasible for 90 patients and PCR-DNA was positive in 20 and BACTEC in eight patients. Out of 20 patients with PCR positive results, 15 were only PCR positive and were subjected to hyster-laparoscopy and five had evidence of tuberculosis. Thus, none of the available tests can pick up all cases of genital tuberculosis, but conventional methods i.e., histopathology and LJ culture still has an important role in the diagnosis of endometrial tuberculosis in government setups where BACTEC and PCR are not performed routinely due to lack of resources.

Pulmonary tuberculosis relapse is defined as these patients that make recurrence of tuberculosis after complete an adequate treatment, and these patients are again diagnosed bacteriologically with tuberculosis. We tried to identify the risk factors for relapse among adults, through an analytical study of cases and controls, with eighty patients among the tuberculosis programmed of Santa Clara Hospital between 1992-2000 with relapse diagnosis which meet criterion of case and eighty patients which meet criterion of control. We did a bivariate analysis with confidence intervals and univariate calculation with logistic regression analysis to predict the development of relapse for the different variables. Diabetes mellitus, chronic renal failure, silicosis are associated with relapse, but in our study we found another factors which are joined to relapse and we suggest that if we find these factors among tuberculosis patients would indicate the chance of relapse and this would create the necessity of use a larger number of doses of antituberculosis medicaments

We investigated the effects of diabetes and the presence of lung cavities on treatment outcomes in patients with pulmonary tuberculosis. We conducted a retrospective review of the clinical records of all consecutive patients admitted to the Kanagawa Cardiovascular and Respiratory Centre with the diagnosis of pulmonary tuberculosis. The study outcomes examined were time to sputum culture conversion and percentage of patients with sputum culture conversion by the time 2 months of treatment, and these outcomes were compared between patients with and without diabetes. Of the 260 patients enrolled in the study, 69 were diagnosed as having diabetes mellitus, while the remaining 191 did not have diabetes. The percentage of patients with cavities was higher in the patients with diabetes (71.0%) than in those without (45.5%; P = 0.0003). The time to sputum culture conversion was significantly longer in the patients with diabetes than in those without (P = 0.0005), and the percentage of patients with a positive sputum culture at 2 months was higher in the patients with diabetes (43.5%) than in those without (18.8%; P = 0.0001). Multivariate analyses revealed that the presence/absence of lung cavities was a more important determinant of treatment outcomes than the presence/absence of diabetes. The presence of lung cavities was found to be a more important determinant of the treatment outcomes than that of diabetes per se in patients with pulmonary tuberculosis. © 2014 The Authors.

To evaluate the CT findings of pulmonary tuberculosis in patients with diabetes mellitus (MD),according to the diabetic control state. Materials and Methods: We retrospectively studied 34 cases of pulmonary tuberculosis accompanied by DM. We divided the right lung three lobes and ten segments and the left into two lobes and eight segments and analyzed CT findings of bronchogenic spread, cavitary lesion, ill-defined nodule, lobular consolidation, lobar and segmental consolidation, atelectasis, interlobular septal thickening, fibrotic band, and associated findings such as lymph node enlargement, pleural effusion and empyema. We also tried to determine the typical CT findings of pulmonary tuberculosis according to diabetic duration and controlled state of DM focusing by FBS 160 and HbA1C 8.0. Results: Among 34 CT scans, bronchogenic spread was seen on 29 (85.3%), cavitary lesion on 26 (76.5%), ill-defined nodules on 11 (32.4%), lobular consolidation on 14 (41.2%), lobar and segmental consolidation on 12 (35.3%), atelectasis on four (14.7%), and fibrotic band on eight (23.5%). Multiple cavities were present in 76.9% of total cavitary lesions, and consolidation with bronchogenic spread in 75%; associated findings were as follows: lymph node enlargement (n=1), pleural effusion (n=10), empyema (n=2), and pericardial effusion (n=2). In 46.7% of cases, general tubercular lesions were in an unusual location, but among cases of secondary pulmonary tuberculosis, 73.9% of lesions were in the usual location. More lobular consolidation was seen in patients with less than FBS 160 on admission, and this result was statistically significant (p<0.05); CT findings did not, however, differ according to diabetic duration and HbA1C. Conclusion: In patients with DM,general fubercular lesions were found infrequently, but in secondary tubereulosis, multiple cavitary lesions-in the usual location-were very frequent. In patients with DM, CT findings of pulmonary tuberculosis did not vary

Objective: To probe into the angiographic signs and the variations of bronchial arteries for pulmonary tuberculosis or bronchiectasis with massive hemoptysis. Methods: 25 patients with pulmonary tuberculosis and 15 patients suffered from bronchiectasis accompanied by massive hemoptysis were undertaken bronchial arterial embolization (BAE). All patients were embolized with gelfoam including 32 with spring coils in addition. Results: 63 arteries demonstrated angiographic signs of hemoptysis in 40 patients. The immediate stanching rate was 92.5%(37/40). The bronchopulmonary shunt formation sign shown by angiograph was the major feature of tuberculosis (P=0.0528) and the enlarged tortuous arteries in bronchiectasis were more to be demonstrated than in tuberculosis (P<0.05). Conclusions: The BAE for patients with tuberculosis ought to be performed in the smaller arteries. BAE for patients with bronchiectasis should to be taken in the trunk of arteries. (authors)

We evaluated the surgical risks associated with fibrocavernous pulmonary tuberculosis by retrospectively examining chest computed tomography (CT) scans. We reviewed the records of 40 patients who underwent pulmonary resection for fibrocavernous pulmonary tuberculosis, for whom preoperative CT scans were available. The disease was categorized as class I, defined as a cavity within one lobe without remarkable pleural thickness, in 21 patients; class II, defined as a cavity extending beyond one lobe or within one lobe with remarkable pleural thickness, in 10 patients; and class III, defined as bilateral cavities, in 9 patients. Four of the nine patients with bilateral cavities underwent bilateral pulmonary resection and five underwent unilateral pulmonary resection. The study parameters were intraoperative blood loss, operative time, hospital stay, major operative morbidity, and hospital death. Intraoperative blood loss and operative time were significantly greater and hospital stay was significantly longer in patients with advanced disease (P=0.046, P=0.000, and P=0.143, respectively). Major surgical morbidity mainly occurred in association with advanced disease (P=0.028) at the following incidences: class I, 5%; class II, 30%; class III, 44.4%. Two hospital deaths occurred, both following bilateral pulmonary resection for class III disease, accounting for an overall 5% mortality rate. The surgical risks associated with fibrocavernous pulmonary tuberculosis were well correlated with anatomic involvement, according to the extent of cavitation and the severity of pleural thickness, as depicted by CT. Staged pulmonary resection or the combination of one-sided resection with other modalities is recommended for the treatment of bilateral cavities. (author)

PRIMARY CONJUNCTIVAL TUBERCULOSIS – A RARE CASE REPORT

Full Text Available Tuberculosis is an endemic disease in India. Primary conjunctival tuberculosis is an uncommon condition and with better treatment of pulmonary tuberculosis it is now becoming extremely rare. Primary conjunctival Tuberculosis can present as unilateral conjunctivitis, hence laterality, chronicity and non-resolution of symptoms on treatment are indications for biopsy. In our patient conjunctival Tuberculosis was diagnosed on histopathology, which resulted in early implementation of antikochs’ treatment and complete resolution of the disease condition.

Coronary to Bronchial Artery Fistula Causing Massive Hemoptysis in Patients with Longstanding Pulmonary Tuberculosis

Energy Technology Data Exchange (ETDEWEB)

Yoon, Ji Young; Jeon, Eui Yong; Lee, In Jae; Koh, Sung Hye [Hallym University College of Medicine, Anyang (Korea, Republic of)

2012-01-15

We report on three cases of longstanding pulmonary tuberculosis patients with coronary to bronchial artery fistula (CBF) who presented with recurrent massive hemoptysis. The first and second patients died because of decreased functional pulmonary volume plus massive hemoptysis and cannulation failure of CBF due to hypovolemic vasospasm, respectively. When recurrent hemoptysis occurs despite successful embolization treatment, CBF should be considered as a potential bleeding source. Moreover, a coronary angiography should be performed, especially in patients with longstanding cardiopulmonary disease such as pulmonary tuberculosis.

Recent studies have shown that thymosin β4 (Tβ4) stimulates angiogenesis by inducing vascular endothelial growth factor (VEGF) expression and stabilizing hypoxia inducible factor-1α (HIF-1α) protein. Pulmonary tuberculosis (TB), a type of granulomatous disease, is accompanied by intense angiogenesis and VEGF levels have been reported to be elevated in serum or tissue inflamed by pulmonary tuberculosis. We investigated the expression of Tβ4 in granulomatous lung tissues at various stages of active pulmonary tuberculosis, and we also examined the expression patterns of VEGF and HIF-1α to compare their Tβ4 expression patterns in patients' tissues and in the tissue microarray of TB patients. Tβ4 was highly expressed in both granulomas and surrounding lymphocytes in nascent granulomatous lung tissue, but was expressed only surrounding tissues of necrotic or caseous necrotic regions. The expression pattern of HIF-1α was similar to that of Tβ4. VEGF was expressed in both granulomas and blood vessels surrounding granulomas. The expression pattern of VEGF co-localized with CD31 (platelet endothelial cell adhesion molecule, PECAM-1), a blood endothelial cell marker, and partially co-localized with Tβ4. However, the expression of Tβ4 did not co-localize with alveolar macrophages. Stained alveolar macrophages were present surrounding regions of granuloma highly expressing Tβ4. We also analyzed mRNA expression in the sputum of 10 normal and 19 pulmonary TB patients. Expression of Tβ4 was significantly higher in patients with pulmonary tuberculosis than in normal controls. These data suggest that Tβ4 is highly expressed in granulomatous lung tissue with active pulmonary TB and is associated with HIF-1α- and VEGF-mediated inflammation and angiogenesis. Furthermore, the expression of Tβ4 in the sputum of pulmonary tuberculosis patients can be used as a potential marker for diagnosis. Copyright © 2014 Elsevier Ltd. All rights reserved.

Tuberculosis (TB) remains a public health problem in Mexico while the incidence of diabetes mellitus type 2 (DM) has increased rapidly in recent years. To describe the trends of incidence rates of pulmonary TB associated with DM and not associated with DM and to compare the results of treatment outcomes in patients with and without DM. We analysed the National Tuberculosis Registry from 2000 to 2012 including patients with pulmonary TB among individuals older than 20 years of age. The association between DM and treatment failure was analysed using logistic regression, accounting for clustering due to regional distribution. In Mexico from 2000 to 2012, the incidence rates of pulmonary TB associated to DM increased by 82.64%, (ppulmonary TB rate without DM, which decreased by 26.77%, (ppulmonary TB. In addition, patients who suffer from both diseases have a greater probability of treatment failure.

Objective: To examine the pulmonary tuberculosis mortality risk of the residents in high background radiation area (HBRA), Yangjiang, China. Methods: A cohort including 89 694 persons in HBRA and 35 385 persons in control area (CA) has been established since 1979. Person-year tables based on classified variables including sex, attained age, follow-up calendar year, and dose-rate group (high, intermediate, and low in HBRA, and control group) were tabulated using DATAB in EPICURE. Poisson regression analysis was used to estimate the relative risks (RR) of infectious and parasitic disease especially for pulmonary tuberculosis. Cumulative dose for each cohort member was obtained. Results: Two million person-years were accumulated by follow-up and 612 cases of pulmonary tuberculosis ascertained. Compared with risk in the control area, statistically significant lower risk of pulmonary tuberculosis was observed in HBRA among those who aged 60 years and over; markedly decreased risk occurred among males; no significant difference was found among the 6 follow-up stages, two subregions in the HBRA, or different diagnostic facilities. A statistically significantly negative dose-response was observed (P<0.001), the higher accumulative dose, the lower dose the pulmonary tuberculosis mortality risk. Its excess relative risk (ERR/Sv) was estimated to be -1.09 (95% CI: -1.34, -0.85). No established risk factors could explain this lower risk. Conclusions: The mortality of puhnonary tuberculosis among residents in HBRA who were chronically exposed to low-dose radiation was statistically significantly lower than that in the control area, and a significant dose-response relationship was observed, which probably resulted from the immunoenhancement of low dose radiation.

Background. Tuberculosis is transmitted by patients with pulmonary disease. Matrix metalloproteinases (MMPs) drive lung destruction in tuberculosis but the resulting matrix degradation products (MDPs) have not been studied. We investigate the hypothesis that MMP activity generates matrix turnover products as correlates of lung pathology. Methods. Induced sputum and plasma were collected prospectively from human immunodeficiency virus (HIV) positive and negative patients with pulmonary tuberculosis and controls. Concentrations of MDPs and MMPs were analyzed by ELISA and Luminex array in 2 patient cohorts. Results. Procollagen III N-terminal propeptide (PIIINP) was 3.8-fold higher in induced sputum of HIV-uninfected tuberculosis patients compared to controls and desmosine, released during elastin degradation, was 2.4-fold higher. PIIINP was elevated in plasma of tuberculosis patients. Plasma PIIINP correlated with induced sputum MMP-1 concentrations and radiological scores, demonstrating that circulating MDPs reflect lung destruction. In a second patient cohort of mixed HIV seroprevalence, plasma PIIINP concentration was increased 3.0-fold above controls (P tuberculosis patients (P = .001). Receiver operating characteristic analysis utilizing these 2 variables demonstrated an area under the curve of 0.832 (P pulmonary tuberculosis, MMP-driven immunopathology generates matrix degradation products.

Pulmonary tuberculosis (TB) can affect lung function, but studies regarding long-term follow-up in patients with no sequelae on chest X-ray (CXR) have not been performed. We evaluated lung functional impairment and persistent respiratory symptoms in those with prior pulmonary TB and those with prior pulmonary TB with no residual sequelae on CXR, and determined risk factors for airflow obstruction. We used data from adults aged ≥ 40 years from the annual Korean National Health and Nutrition Examination Surveys conducted between 2008 and 2012. P values for comparisons were adjusted for age, sex, and smoking status. In total of 14,967 adults, 822 subjects (5.5%) had diagnosed and treated pulmonary TB (mean 29.0 years ago). The FVC% (84.9 vs. 92.6), FEV1% (83.4 vs. 92.4), and FEV1/FVC% (73.4 vs. 77.9) were significantly decreased in subjects with prior pulmonary TB compared to those without (p pulmonary TB (296, 2.3%) had significantly lower FEV1% (90.9 vs. 93.4, p = 0.001) and FEV1/FVC% (76.6 vs. 78.4, p pulmonary TB as well as subjects with no sequalae on CXR were more likely to experience cough and physical activity limitations due to pulmonary symptoms than those without prior pulmonary TB (p pulmonary TB (OR, 2.314; 95% CI, 1.922-2.785), along with age, male, asthma, and smoking mount was risk factor for airflow obstruction. In subjects with prior pulmonary tuberculosis, inactive TB lesion on chest x-ray (OR, 2.300; 95% CI, 1.606-3.294) were risk factors of airflow obstruction. In addition to subjects with inactive TB lesion on CXR, subjects with no sequelae on CXR can show impaired pulmonary function and respiratory symptoms. Prior TB is a risk factor for airflow obstruction and that the risk is more important when they have inactive lesions on chest X-ray. Hence, the patients with treated TB should need to have regular follow-up of lung function and stop smoking for early detection and prevention of the chronic airway disease.

Place and Duration of Study: Department of Pulmonology, Fauji Foundation Hospital, Rawalpindi, from July 2011 to January 2012. Methodology: QuantiFERON-TB gold test (QFT-G) was evaluated and compared it with tuberculin skin test (TST) in 50 cases of active pulmonary tuberculosis, in whom tuberculous infection was suspected on clinical, radiological and microbiological grounds. Sensitivity was determined against positive growth for Mycobacterium tuberculosis. Results: Out of 50 cases, 43 were females and 7 were males. The mean age was 41.84 A+- 19.03 years. Sensitivity of QFT-G was 80% while that of TST was 28%. Conclusion: QFT-G has much higher sensitivity than TST for active pulmonary tuberculosis. It is unaffected by prior BCG administration and prior exposure to atypical mycobacteria. A positive QFT-G result can be an adjunct to diagnosis in patients having clinical and radiological data compatible with pulmonary tuberculosis. (author)

Pulmonary tuberculosis - An emerging risk factor for venous thromboembolism: A case series and review of literature

Amitesh Gupta

2017-01-01

Full Text Available One-third of patients with symptomatic venous thromboembolism (VTE manifest pulmonary embolism, whereas two-thirds manifest deep vein thrombosis (DVT. Overall, 25%–50% of patients with first-time VTE have an idiopathic condition, without a readily identifiable risk factor, and its association with tuberculosis (TB is a rare occurrence. Deep venous thrombosis has been associated with 1.5%–3.4% cases of TB. Early initiation of anti-TB treatment along with anticoagulant therapy decreases the overall morbidity and mortality associated with the disease. We report three cases of DVT associated with pulmonary TB who were diagnosed due to high index of suspicion as the risk factors for the development of DVT were present in these cases.

In this article the authors report a case of a patient with hypertrophic osteoarthropathy associated with pulmonary tuberculosis. This disorder is a rare complication of tuberculosis and may be associated with severe and fulminant disease. The imaging methods used in the diagnosis of this disease included lower limbs radiographs that showed bilateral periosteal reaction, and chest radiographs and computed tomography that revealed a mass in the upper lobe of the right lung. Although a fine needle aspiration was suggestive of tuberculosis, the definitive diagnosis was made after thoracotomy and histopathological examination of the mass. The patient presented symptomatic and radiological improvement after treatment of tuberculosis. (author)

Primary pulmonary tuberculosis in infancy still exists in the urban United States, reflecting new immigrations from less developed areas. The clinical diagnosis may be difficult and routine chest radiographs may be confusing. We found magnification high KV filtered radiography to be very useful in delineating the primary complex and its effect on the tracheobronchial tree. Twelve infants and small children with primary pulmonary tuberculosis were seen in the years 1978-1984. (orig.)

To evaluate the CT features of pulmonary tuberculosis in diabetic or immunocompromised patients, we reviewed CT of the chest in 42 adult patients with active pulmonary tuberculosis. Forty-two had some underlying diseases or immunocompromised conditions (31 diabetes mellitus, 6 malignancies, 2 long-term steroid therapy, 2 pneumoconiosis, and one anorexia nervosa). In diabetic or immunocompromised patients, a high incidence of non-segmental distribution (27%) and multiple small cavities in a cavitary lesion (45%) was observed. Unusual localization of the lesions such as lower lung field disease was observed in 18% of cases (the incidence of unusual localization in patients with no underlying disease was equal to diabetic or immunocompromised patients).

Full Text Available Antimicrobial therapy may cause changes in the resident oral microbiota, with the increase of opportunistic pathogens. The aim of this study was to compare the prevalence of Candida, Staphylococcus, Pseudomonas and Enterobacteriaceae in the oral cavity of fifty patients undergoing antibiotic therapy for pulmonary tuberculosis and systemically healthy controls. Oral rinsing and subgingival samples were obtained, plated in Sabouraud dextrose agar with chloramphenicol, mannitol agar and MacConkey agar, and incubated for 48 h at 37ºC. Candida spp. and coagulase-positive staphylococci were identified by phenotypic tests, C. dubliniensis, by multiplex PCR, and coagulase-negative staphylococci, Enterobacteriaceae and Pseudomonas spp., by the API systems. The number of Candida spp. was significantly higher in tuberculosis patients, and C. albicans was the most prevalent specie. No significant differences in the prevalence of other microorganisms were observed. In conclusion, the antimicrobial therapy for pulmonary tuberculosis induced significant increase only in the amounts of Candida spp.

1989-01-01

The detection of cavity in pulmonary tuberculosis has important roles in its diagnosis, therapy planning and follow-up of healing process, and also means at least moderate advanced tuberculosis. The plain chest film has some limitation of detection of cavity in pulmonary tuberculosis owing to several factors. CT is superior to plain chest film and conventional tomography, in detection of cavitary lesion. Authors retrospectively analyzed CT findings of 20 cases of minimal pulmonary tuberculosis, of which the plain chest films showed no cavitary lesion from Sept. 1986 to July 1988 in Pusan National University Hospital. All cases were proven by culture or AFB test of sputum and clinical evidence. The results were as follows: 1. Sex distribution showed 10 cases (50%) in male, 10 case (50%) in female and the highest incidence in the second decade (40%). 2. All 20 cases showed no cavity on the plain chest films, but all cases showed variable sized cavities on CT. 3. The size of cavities ranged from 4 mm to 30 mm, averaged as 9.9 mm, the thickness of cavitary wall from 3 mm to 8 mm, averaged as 5.8 mm. 4. It is concluded that cavitary lesions which are not visualized on the plain chest films can be demonstrated by CT scan in minimal pulmonary tuberculosis

Zahirifard, S.; Amiri, M.V.; Bakhshayesh Karam, M.; Mirsaeidi, S.M.; Ehsanpour, A.; Masjedi, M.R.

2003-01-01

Background: Multidrug-resistant tuberculosis is a major worldwide health problem. In countries where tuberculosis is of moderate to high prevalence, the issue of Multidrug-resistant tuberculosis carries significant importance. Multidrug-resistant tuberculosis, similar to drug-sensitive tuberculosis, is contagious. Meanwhile its treatment is not only more difficult but also more expensive with lower success rates. Regarding clinical findings, there is no significant difference between Multidrug-resistant tuberculosis and drug-sensitive tuberculosis. Therefore determination of characteristic radiological findings in cases of Multidrug-resistant tuberculosis might be of help in early detection, and hence appropriate management of this disease condition. Objective: To explain the radiological spectrum of pulmonary Multidrug-resistant tuberculosis. Patients and methods: We retrospectively evaluated the radiographic images of 35 patients with clinically-and microbiologically- proven Multidrug-resistant tuberculosis admitted to our tertiary-care tuberculosis unit over a period of 13 months. The latest chest x-ray of all patients and the conventional chest CT scan without contrast of 15 patients were reviewed by three expert radiologists who rendered consensus opinion. Results: Of the 35 patients with imaging studies, 23 (66%) were male and 12 (34%) were female. The mean±SD age of participants was 38.2±17.3 (range: 16-20) years. 33 patients were known as secondary and only 2 had primary Multidrug-resistant tuberculosis. Chest radiography revealed cavitary lesion in 80% pulmonary infiltration in 89% and nodules in 80% of the cases. Pleurisy was the rarest finding observed in only 5 (14%) patients. All of 15 chest CT scans revealed cavitation, 93% of which were bilateral and multiple. Pleural involvement was seen in 93% of patients. Conclusion: Presence of multiple cavities, especially in both lungs, nodular and infiltrative lesions, and pleural effusion are main features

Despite of a clearly defined diagnostic algorithm of pulmonary tuberculosis, low sensibility of contemporary laboratory methods in limited forms of pulmonary tuberculosis contributes to a difficult differential diagnosis with community acquired pneumonia, especially with slowly resolving pneumonia. A case-control, prospective, selective, comparative and descriptive study was performed using a group of 180 patients, divided into two samples: I group - 125 cases with limited form of pulmonary infiltrative tuberculosis; II group - 55 cases with slowly resolving community-acquired pneumonia. The findings identified the prevalence of intoxication syndrome in the slowly resolving pneumonia sample. Lung destructions and bronchogenous dissemination was identified only in the tuberculosis sample. A higher impact of comorbidities and old age was more relevant in slowly resolving pneumonia sample. Clinical and radiological improvement was established in most patients of both groups, but the considerable resorption of lung infiltrates predominated in slowly resolving pneumonia sample.

Deep learning techniques have recently emerged as promising decision supporting approaches to automatically analyze medical images for different clinical diagnosing purposes. Diagnosing of pulmonary nodules by using computer-assisted diagnosing has received considerable theoretical, computational, and empirical research work, and considerable methods have been developed for detection and classification of pulmonary nodules on different formats of images including chest radiographs, computed tomography (CT), and positron emission tomography in the past five decades. The recent remarkable and significant progress in deep learning for pulmonary nodules achieved in both academia and the industry has demonstrated that deep learning techniques seem to be promising alternative decision support schemes to effectively tackle the central issues in pulmonary nodules diagnosing, including feature extraction, nodule detection, false-positive reduction, and benign-malignant classification for the huge volume of chest scan data. The main goal of this investigation is to provide a comprehensive state-of-the-art review of the deep learning aided decision support for pulmonary nodules diagnosing. As far as the authors know, this is the first time that a review is devoted exclusively to deep learning techniques for pulmonary nodules diagnosing.

Lung cancer and pulmonary tuberculosis (TB) are highly prevalent and representing major public health issues. They share common risk factors and clinical manifestations. It is also suggested that TB predicts raised lung cancer risk likely related to chronic inflammation in the lungs. However, it does not seem to influence the clinical course of lung cancer provided that it is properly treated. We present a case report of a 57-year old male with concurrent TB and lung cancer. He was diagnosed with positive sputum smear for acid fast bacilli (AFB) and subsequent culture of Mycobacterium tuberculosis. Besides, his comorbid conditions were chronic hepatitis C virus (HCV) infection and peripheral artery disease (PAD). Later while on anti-tuberculous treatment (ATT) squamous cell lung cancer (SCC) was confirmed with computed tomography (CT) guided biopsy. Due to poor general condition the patient was not fit for either surgery or radical chemo- and radiotherapy. He was transferred to hospice for palliative therapy. We want to emphasize that both TB and lung cancer should be actively sought for in patients with either disorder. In addition, there is no doubt that these patients with lung cancer and with good response to TB treatment should be promptly considered for appropriate anticancer therapy.

Pulmonary tuberculosis is one of the infectious diseases that has been known and is still the leading cause of death in the world. It is an old disease which is a global problem in the world and estimated that a third of the world's population has been infected by this bacterium. The purpose of this study was to determine the factors related with the infection prevention efforts of pulmonary tuberculosis patients in the local goverment clinic of Kuta Baro Aceh Besar. This research is descriptive analytic survey using cross sectional design. It used univariate analysis to see the frequency distribution and the percentage of each variable. Meanwhile, the bivariate analysis used chi square test with CI (Confident Interval) of 95%. The samples in this study are 34 people. The research results obtained with good infection prevention efforts of pulmonary tuberculosis is 41.2%, 5.9% for teenagers, 47.1% for knowledgeable people, 17.6% for people who do not work and 44.1% for those who have a positive behavior. The results of the bivariate obtained there is correlation between the prevention of pulmonary tuberculosis infection with age (p = 0.087), Occupation (p = 0.364), knowledge (p = 0.006) and behavior (p = 0.020). To conclude, there is a correlation between knowledge and behaviors with the infection prevention efforts of pulmonary tuberculosis patients and there is no correlation between age and occupation with infection prevention efforts of pulmonary tuberculosis patients. It is expected that the respondents to hold consultations to health officials about a mechanism of prevention to avoid the disease.

Association of Pulmonary Tuberculosis and Diabetes in Mexico: Analysis of the National Tuberculosis Registry 2000-2012.

Full Text Available Tuberculosis (TB remains a public health problem in Mexico while the incidence of diabetes mellitus type 2 (DM has increased rapidly in recent years.To describe the trends of incidence rates of pulmonary TB associated with DM and not associated with DM and to compare the results of treatment outcomes in patients with and without DM.We analysed the National Tuberculosis Registry from 2000 to 2012 including patients with pulmonary TB among individuals older than 20 years of age. The association between DM and treatment failure was analysed using logistic regression, accounting for clustering due to regional distribution.In Mexico from 2000 to 2012, the incidence rates of pulmonary TB associated to DM increased by 82.64%, (p<0.001 in contrast to rates of pulmonary TB rate without DM, which decreased by 26.77%, (p<0.001. Patients with a prior diagnosis of DM had a greater likelihood of failing treatment (adjusted odds ratio, 1.34 (1.11-1.61 p<0.002 compared with patients who did not have DM. There was statistical evidence of interaction between DM and sex. The odds of treatment failure were increased in both sexes.Our data suggest that the growing DM epidemic has an impact on the rates of pulmonary TB. In addition, patients who suffer from both diseases have a greater probability of treatment failure.

Here are presented the results of a prospective, randomized study regarding the efficiency of regimens with fixed drug combination Rifampicin-Isoniazide manufactured by Antibiotics S.A. of Iasi in comparison with single drugs routinely used in treatment of patients with pulmonary tuberculosis. Newly diagnosed (confirmed by smear and culture) pulmonary tuberculosis patients were selected, and those who accepted to be included in the study, were admitted to the National Institute of Pneumology "Marius Nasta" between August 2001 and September 2002. At the time of admission, they were randomized into two groups: 20 patients received fixed drug combination RMP300 HIN150, and 18 patients received RMP and HIN in single drug tablets (2 patients were excluded). The follow-up of the patients was for one year from the date of enclosure. The smear conversion rate was 83,3% for the patients using single drug tablets, and 70% for those using fixed drug combination, motivated with some more severe TB patterns. The success rate was 100% for all TB patients. Although the present study was done for few patients, we can say that it demonstrated the same efficiency of fixed drug combination produced in Romania, with the single drug tablets, and it suggests a better compliance to treatment with a lower price.

2008-03-01

Full Text Available Abstract Background Although tuberculosis is not uncommon among patients with myelodysplastic syndrome (MDS, only a few reports of such patients suffering from miliary tuberculosis (MT exist. MT often presents as a fever of unknown origin and it is a curable disease, yet fatal if left untreated. Case presentation We report a case of MT with no clinical or laboratory indications of pulmonary involvement in a patient with MDS, and review the relevant literature. Mycobacterium tuberculosis was isolated from the liquid culture of a bone marrow aspirate. Conclusion Even if the initial diagnostic investigation for a fever of obscure etiology is negative, MT should not be excluded from the differential diagnosis list. Since it is a curable disease, persistent and vigorous diagnostic efforts are warranted. In suspected cases, mycobacterial blood cultures should be collected as soon as possible after hospital admission and early bone marrow aspirate with mycobacterial cultures is advocated.

Pulmonary tuberculosis is a deadly infectious disease which occurs in many countries in Asia and Africa. In Indonesia, many people with tuberculosis disease are examined in the community health center. Examination of pulmonary tuberculosis is done through sputum smear with Ziehl - Neelsen staining using conventional light microscope. The results of Ziehl - Neelsen staining will give effect to the appearance of tuberculosis (TB) bacteria in red color and sputum background in blue color. The first examination is to detect the presence of TB bacteria from its color, then from the morphology of the TB bacteria itself. The results of Ziehl - Neelsen staining in sputum smear give the complex color images, so that the clinicians have difficulty when doing slide examination manually because it is time consuming and needs highly training to detect the presence of TB bacteria accurately. The clinicians have heavy workload to examine many sputum smear slides from the patients. To assist the clinicians when reading the sputum smear slide, this research built computer aided diagnose with color image segmentation, feature extraction, and classification method. This research used K-means clustering with patch technique to segment digital sputum smear images which separated the TB bacteria images from the background images. This segmentation method gave the good accuracy 97.68%. Then, feature extraction based on geometrical shape of TB bacteria was applied to this research. The last step, this research used neural network with back propagation method to classify TB bacteria and non TB bacteria images in sputum slides. The classification result of neural network back propagation are learning time (42.69±0.02) second, the number of epoch 5000, error rate of learning 15%, learning accuracy (98.58±0.01)%, and test accuracy (96.54±0.02)%.

Full Text Available Abstract Background Wasting and micronutrient malnutrition have not been well characterized in adults with pulmonary tuberculosis. We hypothesized that micronutrient malnutrition is associated with wasting and higher plasma human immunodeficiency virus (HIV load in adults with pulmonary tuberculosis. Methods In a cross-sectional study involving 579 HIV-positive and 222 HIV-negative adults with pulmonary tuberculosis in Zomba, Malawi, anthropometry, plasma HIV load and plasma micronutrient concentrations (retinol, α-tocopherol, carotenoids, zinc, and selenium were measured. The risk of micronutrient deficiencies was examined at different severity levels of wasting. Results Body mass index (BMI, plasma retinol, carotenoid and selenium concentrations significantly decreased by increasing tertile of plasma HIV load. There were no significant differences in plasma micronutrient concentrations between HIV-negative individuals and HIV-positive individuals who were in the lowest tertile of plasma HIV load. Plasma vitamin A concentrations Conclusions These data demonstrate that wasting and higher HIV load in pulmonary tuberculosis are associated with micronutrient malnutrition.

Primary mediastino pulmonary tuberculosis in infancy is increasing in France. Bacteriological diagnosis is difficult. The aim of the study is to assess the value of chest radiograph and CTscan for diagnosis of tuberculosis. We studied 15 infants, 3 month old to 18 month old, between November 1990 and June 1992. On plain film, lymphadenopathies were present in 13 cases and parenchymal disease in 10 cases, parenchymal nodular densities in 6 cases and pleural effusion in one case, displacement of the trachea in 6 cases. We found CTscan to be useful in delineating the lymphadenopathies and parenchymal changes. In 2 cases lymphadenopathies and in 2 cases alveolar condensation were discovered on CT scan as plain film was normal. In all cases lymphadenopathies were present in CTscan, often in right side and in al cases, lymphadenopathies were hypodense with peripheral enhancement. In conclusion, the association of right paratracheal nodes with displacement of trachea and alveolar consolidation is common in tuberculosis in infants. These findings when seen on chest radiographs must lead to perform a CTscan and suggest the diagnosis. (Authors). 19 refs., 5 figs., 4 tabs

To explore the clinical characteristics and prognostic factors of pulmonary tuberculosis with concurrent lung cancer. Comprehensive analyses were conducted for 58 cases of pulmonary tuberculosis patients with lung cancer. Their clinical symptoms, signs and imaging results were analyzed between January 1998 and January 2005 at Qingdao Chest Hospital. Kaplan-Meier method was utilized to calculate their survival rates. Nine prognostic characteristics were analyzed. Single factor analysis was performed with Logrank test and multi-factor analysis with Cox regression model. The initial symptoms were cough, chest tightness, fever and hemoptysis. Chest radiology showed the coexistence of two diseases was 36 in the same lobe and 22 in different lobes. And there were pulmonary nodules (n = 24), cavities (n = 19), infiltration (n = 8) and atelectasis (n = 7). According to the pathological characteristics, there were squamous carcinoma (n = 33), adenocarcinoma (n = 17), small cell carcinoma (n = 4) and unidentified (n = 4) respectively. The TNM stages were I (n = 13), II(n = 22), III (n = 16) and IV (n = 7) respectively. The median survival period was 24 months. And the 1, 3, 5-year survival rates were 65.5%, 65.5% and 29.0% respectively. Single factor analysis showed that lung cancer TNM staging (P = 0.000) and tuberculosis activity (P = 0.024) were significantly associated with patient prognosis. And multi-factor analysis showed that lung cancer TNM staging (RR = 2.629, 95%CI: 1.759-3.928, P = 0.000) and tuberculosis activity (RR = 1.885, 95%CI: 1.023-3.471, P = 0.042) were relatively independent prognostic factors. The clinical and radiological characteristics contribute jointly to early diagnosis and therapy of tuberculosis with concurrent lung cancer. And TNM staging of lung cancer and activity of tuberculosis are major prognostic factors.

In spanish prisons, tuberculosis is a serious problem of public health and health authorities don't take it seriously. To prove the efficiency of pulmonary tuberculosis case-finding on arrival at prison in order to get location resources in this activity. Cost-benefit analysis of a case-finding program compared with to wait for diagnostic to illness. The sensitivity of test was fixed in 80% and the specificity in 99.99%. The cost was based on market prices. Sensitivity analysis was done in every variables as well as tridimensional analysis in those one of more influence. The case-finding was efficient on prevalences of tuberculosis over 5 per mil. Its efficiency was hardly affected by discount social rates or the sensitivity of diagnostic tests. The prevalence of illness, the cost of diagnostic activities as well as the success of treatment and the specificity of diagnostic tests used had as influence on the efficiency model. The tridimensional analysis proved that the case-finding of pulmonary tuberculosis has efficiency on low prevalences (1 per thousand), provided the number of people cured is a 5% higher than the alternative one and the costs of case-finding less than 1,000 pesetas per subject. The case-finding pulmonary tuberculosis on arrival at prisons is of high efficiency. In a cost-opportunity situation (location of available resources, penitentiary and extrapenitentiary) the program is very efficacious taking into account the fact of higher prevalence of pulmonary tuberculosis in this people.

South Korea has an increasing prevalence of diabetes and a relatively high burden of tuberculosis. We aimed to determine the prevalence of diabetes in patients with active pulmonary tuberculosis (PTB) and examine the effect of diabetes on tuberculosis treatment outcomes. Data from patients ≥30 years diagnosed with and treated for PTB between January 2010 and December 2012 at Severance Hospital, a 2000-bed tertiary referral hospital in Seoul, South Korea, were analyzed and compared with data from a contemporaneous general population sample extracted from KNHANES V. Diabetes prevalence was 24.2% (252/1044) among patients with PTB and 11.6% (1700/14,655) among controls. Diabetes [odds ratios (OR) 2.56, 95% confidence interval (CI) 1.56-4.21, P Diabetes was the only factor associated with unsuccessful treatment outcomes (OR 1.67, 95% CI 1.03-2.70, P = 0.039). The prevalence of diabetes was markedly higher in patients with PTB than in a sample of the general South Korean population. Diabetes may delay sputum conversion and adversely affect treatment outcomes; detection and management of diabetes in patients with PTB is crucial.

Objective: This study was designed to investigate the sensitivity and specificity of magnetic resonance pulmonary perfusion imaging (MRPP) in diagnosing pulmonary embolism (PE) compared with enhanced magnetic resonance pulmonary angiography (MRPA) and pulmonary radionuclide perfusion imaging. Methods: Fourteen patients were definitely diagnosed as PE, whose ages were from 19 to 71 years old and mean 45.5 ± 19.8 years old. All patients under went MRPA and MRPP and 3 patients were examined again after thrombolytic treatment. Five patients underwent pulmonary radionuclide perfusion imaging. Setting ROI in top, middle, bottom of lung area and abnormal area respectively, we detected signal intensity and time-signal curve to obtain the transformation rate of signal (TROS) during perfusion peak value. Results: In 14 pulmonary embolism patients, MRPA found 62 branches of pulmonary artery obstruction. Fifty-five abnormal pulmonary perfusion zones were found by MRPP, and the above results were very alike. The coincidence was 88.71%. In 14 cases, MRPP could show 25 subsegments lesion below segments. In 5 patients who had both results Of MRPP and ECT at the same time. MRPP shows 33 perfusion defect zones and 37 segments were found by ECT, the sensitivity was 89.19%. After thrombolytic treatment, both the status of the affected pulmonary artery improved markedly and perfusion defect zones reduced obviously in 3 cases by MRPP and MRPA. TROS in normal perfusion zones perfusion defect zones and low perfusion zones had significant difference (t=22.882, P<0.01). Conclusion: Contrast enhanced MR pulmonary perfusion can show both perfusion defect zones and low perfusion zones in pulmonary embolism. Time-signal curve can show the period of maximum no perfusion zones in pulmonary artery embolism zones. And the amplitude of fluctuation is small with miminum TROS. MRPP has significant values especially in showing pulmonary artery embolism in segments and subsegments. Using both MRPP and

Full Text Available BACKGROUND: The global tuberculosis epidemic results in nearly 2 million deaths and 9 million new cases of the disease a year. The vast majority of tuberculosis patients live in developing countries, where the diagnosis of tuberculosis relies on the identification of acid-fast bacilli on unprocessed sputum smears using conventional light microscopy. Microscopy has high specificity in tuberculosis-endemic countries, but modest sensitivity which varies among laboratories (range 20% to 80%. Moreover, the sensitivity is poor for paucibacillary disease (e.g., pediatric and HIV-associated tuberculosis. Thus, the development of rapid and accurate new diagnostic tools is imperative. Immune-based tests are potentially suitable for use in low-income countries as some test formats can be performed at the point of care without laboratory equipment. Currently, dozens of distinct commercial antibody detection tests are sold in developing countries. The question is "do they work?" METHODS AND FINDINGS: We conducted a systematic review to assess the accuracy of commercial antibody detection tests for the diagnosis of pulmonary tuberculosis. Studies from all countries using culture and/or microscopy smear for confirmation of pulmonary tuberculosis were eligible. Studies with fewer than 50 participants (25 patients and 25 control participants were excluded. In a comprehensive search, we identified 68 studies. The results demonstrate that (1 overall, commercial tests vary widely in performance; (2 sensitivity is higher in smear-positive than smear-negative samples; (3 in studies of smear-positive patients, Anda-TB IgG by enzyme-linked immunosorbent assay shows limited sensitivity (range 63% to 85% and inconsistent specificity (range 73% to 100%; (4 specificity is higher in healthy volunteers than in patients in whom tuberculosis disease is initially suspected and subsequently ruled out; and (5 there are insufficient data to determine the accuracy of most

Background and Objectives

Culture of M. tuberculosis is the golden standard for the diagnosis of TB which is a much more sensitive test than Smear examination. There is a strong need to use the new assays in order to speed up diagnostic methods. The aim of this research was to determine the evaluation of Microscopic Observation Drug Susceptibility culture in pulmonary tuberculosis in comparison with Ziehl-Neelsen stain and Lowenstein-Jensen culture of sputum.

Methods

The research method was a Cross-sectional (diagnostic test and the technique was observational-interview type. If the patient's history revealed clinical criteria compatible with TB and the infectious specialist’s judgment was that of "TB suspected case, the patient was considered a pulmonary TB suspect. Then, in addition to sputum Ziehl-Neelsen stain and culture for Lowenstein-Jensen, we carried out MODS culture as well.

Results

100 patients (48 male, 52 female with mean age of 52.9 ± 21.83 were evaluated. During sputum examination, 40% were Ziehl-Neelsen stain positive while 30% had positive sputum culture for Mycobacterium Tuberculosis in Lowenstein-Jensen and 47% had positive MODS culture. In comparison with sputum smear and Lowenstein-Jensen culture, MODS had a sensitivity of 82.5% and 86%, specificity of 77% and 70%, positive predictive value of 70% and 55%, negative predictive value of 86% and 92%, respectively.

Tuberculosis (TB) is a major global health problem, which has been ranked as the second leading cause of death from an infectious disease worldwide. Diagnosis based on cultured specimens is the reference standard, however results take weeks to process. Scientists are looking for early detection strategies, which remain the cornerstone of tuberculosis control. Consequently there is a need to develop an expert system that helps medical professionals to accurately and quickly diagnose the disease. Artificial Immune Recognition System (AIRS) has been used successfully for diagnosing various diseases. However, little effort has been undertaken to improve its classification accuracy. In order to increase the classification accuracy of AIRS, this study introduces a new hybrid system that incorporates a support vector machine into AIRS for diagnosing tuberculosis. Patient epacris reports obtained from the Pasteur laboratory of Iran were used as the benchmark data set, with the sample size of 175 (114 positive samples for TB and 60 samples in the negative group). The strategy of this study was to ensure representativeness, thus it was important to have an adequate number of instances for both TB and non-TB cases. The classification performance was measured through 10-fold cross-validation, Root Mean Squared Error (RMSE), sensitivity and specificity, Youden's Index, and Area Under the Curve (AUC). Statistical analysis was done using the Waikato Environment for Knowledge Analysis (WEKA), a machine learning program for windows. With an accuracy of 100%, sensitivity of 100%, specificity of 100%, Youden's Index of 1, Area Under the Curve of 1, and RMSE of 0, the proposed method was able to successfully classify tuberculosis patients. There have been many researches that aimed at diagnosing tuberculosis faster and more accurately. Our results described a model for diagnosing tuberculosis with 100% sensitivity and 100% specificity. This model can be used as an additional tool for

Setting Detection of smear-positive pulmonary tuberculosis (PTB) cases is vital for tuberculosis control. Methods to augment sputum collection are available but their additional benefit is uncertain in resource-limited settings. Objective To compare the diagnostic yields using five methods to obtain sputum from adults diagnosed with smear-negative PTB in Malawi. Design Self-expectorated sputum was collected under supervision for microscopy and mycobacterial culture in the study laboratory. Confirmed smear-negative patients, provided physiotherapy-assisted sputum and induced sputum followed, the next morning, by gastric washing and bronchoalveolar-lavage samples. Results 150 patients, diagnosed with smear-negative PTB by the hospital service, were screened. 39 (26%) were smear-positive from supervised self-expectorated sputum examined in the study laboratory. The remaining 111 confirmed smear-negative patients were enrolled; 89% were HIV positive. Seven additional smear-positive cases were diagnosed using the augmented sputum collection techniques. No differences were observed in the numbers of cases detected using the different methods. 44 (95.6%) of the 46 smear-positive cases could be detected from self-expectorated and physiotherapy-assisted samples Conclusions For countries like Malawi, the best use of limited resources to detect smear-positive PTB cases would be to improve the quality of self-expectorated sputum collection and microscopy. The additional diagnostic yield using bronchoalveolar-lavage after induced sputum is limited. PMID:19105886

To determine the length of delays from onset of symptoms to initiation of treatment of pulmonary tuberculosis (PTB). Cross-sectional study. Chest/TB clinic, Moi Teaching and Referral Hospital (MTRH), Eldoret, Kenya. Newly diagnosed smear positive pulmonary tuberculosis (PTB) patients. Two hundred and thirty patients aged between 12 and 80 (median; 28.5) years were included in the study. They comprised 148 (64.3%, median 30 years) males and 82 (35.7%, median 28 years) females. One hundred and two (44%) came from urban and 128 (56%) came from rural setting covering a median distance of 10 (range 0-100) kilometres and paying Kshs 20 (range 0-200) to facility. Cough was the commonest symptom reported by 228 (99.1%) of the patients followed by chest pain in 214 (80%). The mean patient delay was 11 +/- 17 weeks (range: 1-78 weeks) with no significant difference between males and females, the mean system delay was 3 +/- 5 weeks (range: 0-39 weeks). The median patient, health systems and total delays were 42, 2, and 44 days respectively for all the patients. Marital status, being knowledgeable about TB, distance to clinic and where help is sought first had significant effect on patient delay. Patient delay is the major contributor to delay in diagnosis and initiation of treatment of PTB among our patients. Therefore TB control programmes in this region must emphasise patient education regarding symptoms of tuberculosis and timely health seeking behaviour.

Despite the high efficacy of tuberculosis (TB) drug regiments, one of the barriers in the TB control program is the non-compliance to treatment. Morbidity, mortality, and risk to become resistant to drugs are emerging among defaulters. Thus, the aim of this study is to identify the factors, especially knowledge and perceptions of TB and association with treatment default among patients treated in primary care settings, East Nusa Tenggara. This study was part of a bigger cohort community-based controlled trial study. The subjects were newly diagnosed pulmonary TB patients from four districts in East Nusa Tenggara. Knowledge, perception of TB, and other related factors were assessed prior to the treatment. Patients who interrupted the treatment in two consecutive months were classified as defaulters, as World Health Organization stated. Odds ratio (OR) looking for factors associated with becoming defaulter was analyzed. A total of 300 patients were recruited for this study. At the end of the treatment, 255 patients (85%) completed the treatment without interruption from regular visit. In univariate analysis, none of the socio-demographic factors attributed to treatment default yet lack of knowledge and incorrect perception of TB prior therapy (OR 2.49 1.30-4.79 95% CI, p = 0.006; OR 5.40 2.64-11.04 95% CI, p default (OR 4.75 2.30-9.86 95% CI). Assessing the knowledge and perception of TB prior to the treatment in newly pulmonary TB patients is important as both of them were known as risk factor for treatment default. Education and counseling may be required to improve patients' compliance to treatment.

This study identified urinary biomarkers for tuberculosis (TB) diagnosis. The urine proteomic profiles of 45 pulmonary tuberculosis patients prior to anti-TB treatment and 45 healthy controls were analyzed and compared using two-dimensional electrophoresis with matrix-assisted laser desorption/ionization time of flight mass spectrometry. Nineteen differentially expressed proteins were identified preliminarily, and western blotting and qRT-PCR were performed to confirm these changes at the translational and transcriptional levels, respectively, using samples from 122 additional pulmonary tuberculosis patients and 73 additional healthy controls. Two proteins, mannose-binding lectin 2 and a 35-kDa fragment of inter-α-trypsin inhibitor H4, exhibited the highest differential expression. We constructed a protein-microRNA interaction network that primarily involved complement and inflammatory responses. Eleven microRNAs from microRNA-target protein interactions were screened and validated using qRT-PCR with some of the above samples, including 97 pulmonary tuberculosis patients and 48 healthy controls. Only miR-625-3p exhibited significant differential expression (p tuberculosis diagnosis than individual biomarkers or any two-biomarker combination and generated a diagnostic sensitivity of 85.87% and a specificity of 87.50%. These novel urine biomarkers may significantly improve tuberculosis diagnosis.

Full Text Available Abstract Background In Ethiopia where there is no strong surveillance system and state of the art diagnostic facilities are limited, the real burden of tuberculosis (TB is not well known. We conducted a community based survey to estimate the prevalence of pulmonary TB and spoligotype pattern of the Mycobacterium tuberculosis isolates in Southwest Ethiopia. Methods A total of 30040 adults in 10882 households were screened for pulmonary TB in Gilgel Gibe field research centre in Southwest Ethiopia. A total of 482 TB suspects were identified and smear microscopy and culture was done for 428 TB suspects. Counseling and testing for HIV/AIDS was done for all TB suspects. Spoligotyping was done to characterize the Mycobacterium tuberculosis isolates. Results Majority of the TB suspects were females (60.7% and non-literates (83.6%. Using smear microscopy, a total of 5 new and 4 old cases of pulmonary TB cases were identified making the prevalence of TB 30 per 100,000. However, using the culture method, we identified 17 new cases with a prevalence of 76.1 per 100,000. There were 4.3 undiagnosed pulmonary TB cases for every TB case who was diagnosed through the passive case detection mechanism in the health facility. Eleven isolates (64.7% belonged to the six previously known spoligotypes: T, Haarlem and Central-Asian (CAS. Six new spoligotype patterns of Mycobacterium tuberculosis, not present in the international database (SpolDB4 were identified. None of the rural residents was HIV infected and only 5 (5.5% of the urban TB suspects were positive for HIV. Conclusion The prevalence of TB in the rural community of Southwest Ethiopia is low. There are large numbers of undiagnosed TB cases in the community. However, the number of sputum smear-positive cases was very low and therefore the risk of transmitting the infection to others may be limited. Active case finding through health extension workers in the community can improve the low case detection rate

Full Text Available Background: In South Africa, pulmonary tuberculosis (PTB remains a problem of epidemic proportions. Despite evidence demonstrating persistent lung impairment after PTB cure, few population-based South African studies have investigated this finding. Pulmonary rehabilitation post-cure is not routinely received. Objectives: To determine the effects of PTB on lung function in adults with current or past PTB. To determine any association between PTB and chronic obstructive pulmonary disease (COPD. Methods: This study was observational and cross-sectional in design. Participants (n = 55 were included if they were HIV positive on treatment, had current PTB and were on treatment, and/or had previous PTB and completed treatment or if they were healthy adult subjects with no history of PTB. A sample of convenience was used with participants coming from a similar socio-economic background and undergoing spirometry testing. Multiple regression analyses were conducted on each lung function variable. Results: Compared to normal percentage-predicted values, forced expiratory volume in 1 second (FEV1 , forced vital capacity (FVC and FEV1 :FVC were significantly reduced in those with current PTB by 23.39%, 15.99% and 6.4%, respectively. Both FEV1 and FVC were significantly reduced in those with past PTB by 11.76% and 10.79%, respectively. There was no association between PTB and COPD – those with previous PTB having a reduced FEV1 :FVC (4.88% less than the norm, which was just short of significance (p = 0.059. Conclusions: Lung function is reduced both during and after treatment for PTB and these deficits may persist. This has implications regarding the need for pulmonary rehabilitation even after medical cure. Keywords: Lung function, pulmonary, tuberculosis

This study examined 40 patients: 34 have pulmonary tuberculosis, 3 have pneumonitis, 2 have lung cancer, and one has bilharziasis. All patients have been imaged using radioisotopes compounds (99mTc-infecton and 99mTcHIG) and after 1 hour and 4 hours of patients injection.Using 99mTc-infecton gave positive results in 30 pulmonary tuberculosis patients out of 34, the 3 pneumonitis patients, while using 99mTcHIG gave positive results in 27 pulmonary tuberculosis patients including the 3 pneumonitis patients. Both 99mTc-infecton and 99mTcHIG gave negative results with the lung cancer patients and unreal positive results with the bilharziasis patient. It has been found that the sensitivity and accuracy in the examinations using 99mTc-infecton were 88%, 93%, and 85.7% respectively in comparison with using 99mTcHIG where the values were 70.6%, 91%, and 68.5% respectively. Continuing examination and monitoring of 18 tuberculosis patients for 2-18 months with anti-pulmonary tuberculosis treatment, showed complete response of 12 patients using 99mTc-infecton, and 8 by using 99mTcHIG. As a result, 99mTc-infecton can be used for examining pulmonary tuberculosis patients

Full Text Available Pulmonary actinomycosis is a rare disease that is often misdiag-nosed as tuberculosis or lung cancer. Actinomyces graevenitzii is a relatively new recognized Actinomyces species isolated from various clinical samples. The authors report a case of pulmonary actinomycosis caused by A graevenitzii. A computed tomography examination revealed an excavated consolidation in the middle right lobe of a previously healthy young man who presented with a long history of moderate cough. Cultures of the bronchoalveolar lavage fluid confirmed the diagnosis of pulmonary abscess caused by A gravenitzii. At the three-month follow-up consultation and, after six weeks of high-dose amoxicillin, the pulmonary lesion had completely disappeared.

The objective of this study was to use high-resolution computed tomography (HRCT) imaging to predict the presence of smear-positive active pulmonary tuberculosis (PTB) in elderly (at least 65 years of age) and non-elderly patients (18-65 years of age). Patients with active pulmonary infections seen from November 2010 through December 2011 received HRCT chest imaging, sputum smears for acid-fast bacilli and sputum cultures for Mycobacterium tuberculosis. Smear-positive PTB was defined as at least one positive sputum smear and a positive culture for M. tuberculosis. Multivariate logistic regression analyses were performed to determine the HRCT predictors of smear-positive active PTB, and a prediction score was developed on the basis of receiver operating characteristic curve analysis. Of 1,255 patients included, 139 were diagnosed with smear-positive active PTB. According to ROC curve analysis, the sensitivity, specificity, positive predictive value, negative predictive value, false positive rates and false negative rates were 98.6 %, 95.8 %, 78.5 %, 99.8 %, 4.2 % and 1.4 %, respectively, for diagnosing smear-positive active PTB in elderly patients, and 100.0 %, 96.9 %, 76.5 %, 100.0 %, 3.1 % and 0.0 %, respectively, for non-elderly patients. HRCT can assist in the early diagnosis of the most infectious active PTB, thereby preventing transmission and minimizing unnecessary immediate respiratory isolation. (orig.)

Tuberculosis is a rare but serious complication after transplantation. We report a case and discuss its presentation and management. A 60-year-old Indonesian male presented initially with fever, acute confusion and rapidly progressive right upper lobe pneumonia 3.5 months post-liver transplant, and was diagnosed with pulmonary tuberculosis by positive sputum smear for acid-fast bacilli and tuberculosis culture. Standard anti-tuberculosis therapy was administered but was complicated by interaction with cyclosporine and drug-induced cholestasis. A high level of suspicion, prompt antituberculosis treatment and close follow-up are essential in management of post-transplant tuberculosis.

Full Text Available This study evaluated differences in AIDS patients with and without tuberculosis (TB in Espírito Santo State, Brazil. Standard regional AIDS (SINAN, SISCEL, SICLOM and SIM and tuberculosis (SINAN databases were used. TB and AIDS databases were linked using Reclink software, version 3, with SPSS software support to identify co-infected cases. Data from July 2000 to June 2006 in Espírito Santo State were linked. The results showed 3,523 adult AIDS cases and 9,958 adult TB cases resulted in 430 co-infected patients, who were compared to 1,290 AIDS patients who never developed TB. Among 430 co-infected patients, TB was diagnosed first in 223 (51.9%, AIDS was first in 44 (10.2%, and AIDS and TB were diagnosed concurrently in 163 (37.9%. Median age did not differ between co-infected cases (36 years (interquartile range [IQR] 29-43 and non-co-infected cases (34 years; IQR 28-42. Pulmonary tuberculosis was diagnosed in 239 (55.6%; 109 (25.3% had extra-pulmonary TB and 82 (19.1% had both presentations.

There have been scarce data evaluating the differences of clinical characteristics and prognosis of chronic pulmonary aspergillosis (CPA) depending on underlying pulmonary diseases. We tried to clarify them in CPA patients who had pulmonary emphysema or previous pulmonary tuberculosis. We reviewed and evaluated CPA patients diagnosed between 2007 and 2013 with pulmonary emphysema (PE group; n = 29), with previous pulmonary tuberculosis (PT group; n = 47) and with combination of these 2 underlying conditions (CTE group; n = 24). In CT findings, fungus balls were rare in PE group (7% in PE group and 36% in PT group; p = 0.006). Compared with PT group, PE group patients exhibited more frequent preceding antibiotics administration (45% vs 11%; p = 0.002) and fever (52% vs 17%; p = 0.002), less frequent hemosputum (24% vs 57%; p = 0.008), and more frequent consolidations in imaging (79% vs 38%; p = 0.001) and respiratory failure (34% vs 13%; p = 0.020), possibly suggesting more acute clinical manifestations of CPA in emphysematous patients. Trend of the differences between PT and PE group was not changed when patients with fungal balls were excluded. Multivariate Cox regression analysis of risks for all-cause mortality revealed age (HR, 1.079; p = 0.002) and emphysema (HR, 2.45; p = 0.040) as risk factors. Assessment of underlying lung diseases is needed when we estimate prognosis and consider treatment of CPA patients. Particularly, emphysematous patients can be presented as refractory pneumonia and show poor prognosis.

2012-01-01

Objective: To investigate clinical effect of bronchial artery embolization (BAE) in treating massive hemoptysis due to pulmonary tuberculosis and to analyze the causes of recurrence in order to improve the therapeutic results. Methods: A total of 39 cases of patients with recurrent massive hemoptysis due to pulmonary tuberculosis, who were encountered during the period from Oct. 2007 to Sep. 2010, were enrolled in this study. The lesions included infiltrative pulmonary tuberculosis (n= 28) and chronic fibrocavitary pulmonary tuberculosis (n= 11). BAE with polyvinyl alcohol (PVA) particles only was performed in 14 cases (group A), while BAE with both PVA particles and coils was carried out in 25 cases (group B). All the patients were followed up for 12 - 48 months. The results were compared between the two groups. Results: Immediate hemostasis was obtained in 36 cases (92.3%), the clinical result was excellent in 3 cases. The complete cure or excellent result with single embolization procedure was achieved in 30 cases (76.9%). Recurrence was seen in 9 cases (23.1%). The difference in the recurrence rate between group A (42.9%) and group B (12.0%) was statistically significant (P < 0.05). The relapsing rate of patients with chronic fibrocavitary pulmonary tuberculosis was significantly higher than that of patients with infiltrative pulmonary tuberculosis (45.5% vs. 14.3%, P < 0.05). Conclusion: BAE has an instant effect of hemostasis and satisfactory clinical result. Nowadays BAE has already become the treatment of first choice for hemoptysis caused by pulmonary tuberculosis. The dual embolization technique with the combination use of PVA particles and coils can effectively reduce the recurrence of' pulmonary tuberculosis hemoptysis. (authors)

Cellular immune responses to ESAT-6 discriminate between patients with pulmonary disease due to Mycobacterium avium complex and those with pulmonary disease due to Mycobacterium tuberculosis

DEFF Research Database (Denmark)

Lein, A D; von Reyn, C F; Ravn, P

ESAT-6 (for 6-kDa early secreted antigenic target) is a secreted antigen found almost exclusively in organisms of the Mycobacterium tuberculosis complex. We compared in vitro gamma interferon (IFN-gamma) responses by peripheral blood mononuclear cells to this antigen in patients with pulmonary...... disease due to either Mycobacterium avium complex (MAC) or Mycobacterium tuberculosis with those in healthy, skin test-negative, control subjects. Significant IFN-gamma responses to ESAT-6 were detected in 16 (59%) of 27 M. tuberculosis pulmonary disease patients, 0 (0%) of 8 MAC disease patients, and 0...... (0%) of 8 controls. Significant IFN-gamma responses to M. tuberculosis purified protein derivative were detected in 23 (85%) of 27 M. tuberculosis disease patients, 2 (25%) of 8 MAC disease patients, and 5 (63%) of 8 healthy controls. M. avium sensitin was recognized in 24 (89%) of 27 M. tuberculosis...

Diagnosing the underlying cause of acute dyspnea can be challenging. Lung ultrasound may help to identify pulmonary edema as a possible cause. To evaluate the ability of residents to recognize pulmonary edema on lung ultrasound using chest radiographs as a comparison standard. This is a prospective, blinded, observational study of a convenience sample of resident physicians in the Departments of Emergency Medicine (EM), Internal Medicine (IM), and Radiology. Residents were given a tutorial on interpreting pulmonary edema on both chest radiograph and lung ultrasound. They were then shown both ultrasounds and chest radiographs from 20 patients who had presented to the emergency department with dyspnea, 10 with a primary diagnosis of pulmonary edema, and 10 with alternative diagnoses. Cohen's κ values were calculated to describe the strength of the correlation between resident and gold standard interpretations. Participants included 20 EM, 20 IM, and 20 Radiology residents. The overall agreement with gold standard interpretation of pulmonary edema on lung ultrasound (74%, κ = 0.51, 95% confidence interval 0.46-0.55) was superior to chest radiographs (58%, κ = 0.25, 95% confidence interval 0.20-0.30) (P Radiology residents interpreted chest radiographs more accurately than did EM and IM residents. Residents were able to more accurately identify pulmonary edema with lung ultrasound than with chest radiograph. Physicians with minimal exposure to lung ultrasound may be able to correctly recognize pulmonary edema on lung ultrasound.

Sputum induction, bronchoalveolar lavage, or gastric aspiration are often needed to produce adequate diagnostic respiratory samples from people with HIV in whom tuberculosis is suspected. Since these procedures are rarely appropriate in less-developed countries, we compared the performances of a simple string test and the gold-standard sputum induction. 160 HIV-positive adults under investigation for tuberculosis, and 52 asymptomatic HIV-positive control patients underwent the string test followed by sputum induction. The string test detected tuberculosis in 14 patients in whom this disease was suspected; sputum induction detected only eight of them (McNemar's test, p=0·03). These preliminary data suggest that the string test is safe and effective for retrieval of useful clinical specimens for diagnosis of pulmonary tuberculosis, and is at least as sensitive as sputum induction.

2014-11-01

This article analyzes the concept of inactive fibrotic lesions of presumed tuberculous origin (old healed tuberculosis), defined by radiological characteristics and a positive tuberculin skin test (TST), and we examine the evidence-based foundation for the indication of treatment of latent tuberculosis infection in these cases. We explore the risk of reactivation in older and recent literature, and the problems raised by the differential diagnosis with active tuberculosis with negative bacteriology. We also analyze data on the prevalence of fibrotic lesions in the recent literature. We examine the possible role of Interferon Gamma Release Assays (IGRAs) versus TST and other molecular antigen detection techniques in sputum that can aid in establishing the diagnosis and we discuss the current indications for chemoprophylaxis and the different options available. We propose diagnostic guidelines and therapeutic algorithms based on risk stratification by age and other factors in the management of radiological lesions that raise a differential diagnosis between fibrotic lesions and active pulmonary tuberculosis with negative bacteriology.

Background Host pathogen relationships can be classified as allopatric, when the pathogens originated from separate, non-overlapping geographic areas from the host; or sympatric, when host and pathogen shared a common ancestral geographic location. It remains unclear if host–pathogen relationships, as defined by phylogenetic lineage, influence clinical outcome. We sought to examine the association between allopatric and sympatric phylogenetic Mycobacterium tuberculosis lineages and pulmonary impairment after tuberculosis (PIAT). Methods Pulmonary function tests were performed on patients 16 years of age and older who had received ≥20 weeks of treatment for culture-confirmed M. tuberculosis complex. Forced Expiratory Volume in 1 min (FEV1) ≥80%, Forced Vital Capacity (FVC) ≥80% and FEV1/FVC >70% of predicted were considered normal. Other results defined pulmonary impairment. Spoligotype and 12-locus mycobacterial interspersed repetitive units-variable number of tandem repeats (MIRU-VNTR) were used to assign phylogenetic lineage. PIAT severity was compared between host–pathogen relationships which were defined by geography and ethnic population. We used multivariate logistic regression modeling to calculate adjusted odds ratios (aOR) between phylogenetic lineage and PIAT. Results Self-reported continental ancestry was correlated with Mycobacterium. tuberculosis lineage (p allopatric host–pathogen relationships and PIAT was 1.8 (95% confidence interval [CI]: 1.1, 2.9) compared to sympatric relationships. Smoking >30 pack-years was also associated with PIAT (aOR: 3.2; 95% CI: 1.5, 7.2) relative to smoking allopatric–host–pathogen relationship were more likely to have PIAT than patients with disease from sympatric–host–pathogen relationship infection. Further study of this association may identify ways that treatment and preventive efforts can be tailored to specific lineages and racial/ethnic populations. PMID:23501297

Orchestration of pulmonary T cell immunity during Mycobacterium tuberculosis infection: immunity interruptus

2014-01-01

Despite the introduction almost a century ago of Mycobacterium bovis BCG (BCG), an attenuated form of M. bovis that is used as a vaccine against Mycobacterium tuberculosis, tuberculosis remains a global health threat and kills more than 1.5 million people each year. This is mostly because BCG fails to prevent pulmonary disease – the contagious form of tuberculosis. Although there have been significant advances in understanding how the immune system responds to infection, the qualities that define protective immunity against M. tuberculosis remain poorly characterized. The ability to predict who will maintain control over the infection and who will succumb to clinical disease would revolutionize our approach to surveillance, control, and treatment. Here we review the current understanding of pulmonary T cell responses following M. tuberculosis infection. While infection elicits a strong immune response that contains infection, M. tuberculosis evades eradication. Traditionally, its intracellular lifestyle and alteration of macrophage function are viewed as the dominant mechanisms of evasion. Now we appreciate that chronic inflammation leads to T cell dysfunction. While this may arise as the host balances the goals of bacterial sterilization and avoidance of tissue damage, it is becoming clear that T cell dysfunction impairs host resistance. Defining the mechanisms that lead to T cell dysfunction is crucial as memory T cell responses are likely to be subject to the same subject to the same pressures. Thus, success of T cell based vaccines is predicated on memory T cells avoiding exhaustion while at the same time not promoting overt tissue damage. PMID:25311810

The purpose of our study is to evaluate the plain radiographic features of pulmonary tuberculosis in adult diabetic patients compared with those in patients without any underlying diseases. We analyzed the chest PA and lateral views of 100 patients having active pulmonary tuberculosis; 14 patients had diabetes mellitus and 60 patients had no other underlying diseases. Their images were assesed for anatomical distributions, extents of lesions, size and number of cavity and patterns of radiographic findings. Diabetic tuberculosis had higher prevalence and wider involvement of unusual segments for the tuberculosis such as anterior segment, lingular segment of upper lobe and basal segment of the lower lobe, and they showed the tendency of having more cavities than those who had no other underlying diseases, but there were no meaningful differences in the cavity size between the two groups. Pulmonary tuberculosis in diabetic patients tends to have wider extent with unusual segmental involvement and multiple cavities than in the patients who had no other underlying diseases

Tuberculosis is highly prevalent in Pakistan. It is a contagious disease and causes a lot of morbidity and mortality. Its treatment is costly especially for poor countries like Pakistan. But fortunately it is a preventable disease. Objective of this study was to analyse various epidemiological features of tuberculosis in District Kotli, a remote area of Northern Pakistan. This cross sectional study was conducted in District Kotli, Azad Kashmir from January to December 2009. Data was collected from eight national TB centres of District Kotli. It included all the diagnosed cases of tuberculosis, registered there during the study period. Various epidemiological aspects of these patients were analysed. Total number patients registered during the study period were 752. Of these 579 (76.99%) were pulmonary and 173 (23%) were extra-pulmonary tuberculosis (EPT). Total prevalence of tuberculosis was found to be 100.27 per 100,000. Prevalence of pulmonary TB was 77.2 while that of EPT was 23.07 per 100,000. There were 405 males (53.85%) and 347 females (46.14%). Most patients were 61-75 years of age (220, 29.25%). Overall 417 (55.44%) were 46-75 years. Housewives were affected most frequently (324, 43.08%). Labourers were also commonly involved (40.82%). All cause mortality was 29 (3.85%). Mortality due to tuberculosi as was 11 (1.04%). Among pulmonary tuberculosis, 259 (44.78%) were sputum smear positive and 320) (55.26%) were sputum smear negative. In EPT, most frequent was pleural effusion (74, 42%) and least frequent was skin involvement (3, 1.73%). Prevalence of tuberculosis in Kotli was lower than the overall prevalence in Pakistan. Male to female ratio was lower than that generally observed in Southeast Asia. It was more common in middle to old age population. Frequency was higher in housewives and labourers. Very significant proportion of pulmonary TB was sputum smear positive. Among EPT, pleural effusion was the most common mode of presentation.

Tuberculosis remains a major health problem in India, with 2 million new cases and 421,000 deaths each year. In this paper, we describe the spoligotyping results of 216 Mycobacterium tuberculosis culture isolates from patients with pulmonary tuberculosis in Mumbai, India. As spoligotyping data from India have rarely been described until now, and as there is limited information on the major circulating clades of M. tuberculosis, the data obtained were also compared to an international spoligotype database (SpolDB4) that contained patterns from 22,546 isolates from more than 100 countries. Eighty-four (39%) of the isolates were definitively marked as orphan strains, indicating the paucity of such data from India. The remaining 132 isolates clustered among 59 shared types; among these, 42 shared types were already present in the database, 17 were newly created, and 5 of them were specifically reported from Mumbai. A total of 9 major types in this study clustered 32% of the isolates. At the phylogenetic level, 30% of the isolates belonged to the Central Asian families CAS1 and CAS2, of the major genetic group (MGG) 1, 29% to MGG 2 and 3 families (spacers 33-36 missing) and 17% to the ancestral East African Indian (EAI) family. Finally, nearly 10% of the isolates belonged to the W-Beijing family in a broad sense, also in the MGG 1 group. In conclusion, historic clones of the MGG 1 group of M. tuberculosis are responsible for roughly 60% of all tuberculosis cases in Mumbai. Together with the fact that organisms presumably of European descent (such as the Haarlem family) were only rarely found, our observations suggest that tuberculosis in Mumbai, India is essentially caused by historical clones of tubercle bacilli undergoing active circulation due to uncontrolled demography, high prevalence of the disease, and a paucity of resources.

Magnetic Resonance Imaging of the Lung as an Alternative for a Pregnant Woman with Pulmonary Tuberculosis.

2015-05-01

We report a case of a pregnant 21-year-old woman with pulmonary tuberculosis in which magnetic resonance imaging of the lung was used to assess the extent and characteristics of the pathological changes. Although the lung has been mostly ignored in magnetic resonance imaging for many decades, today technical development enables detailed examinations of the lung. The technique is now entering the clinical arena and its indications are increasing. Magnetic resonance imaging of the lung is not only an alternative method without radiation exposure, it can provide additional information in pulmonary imaging compared to other modalities including computed tomography. We describe a successful application of magnetic resonance imaging of the lung and the imaging appearance of post-primary tuberculosis. This case report indicates that magnetic resonance imaging of the lung can potentially be the first choice imaging technique in pregnant women with suspected pulmonary tuberculosis.

To describe clinical presentation across age groups in 2855 children with pulmonary tuberculosis (TB) attending the Children's Hospital, Lima, Peru, to improve the diagnosis, treatment and care of childhood TB. Children aged 0-14 years admitted between 1 January 1973 and 31 December 1997 with active pulmonary TB were enrolled. Demographic information, history, physical examination data, laboratory and microbiological results, chest radiograph data, disease classification, treatment and adverse effect data, and outcome at the time of discharge were recorded by pulmonologists using detailed chart abstractions. Of the 2855 enrollees, 47% were malnourished and 56% had a household contact. Older children presented with classic TB symptoms, while weight loss and anorexia were rare in children aged <5 years. Microbiological or pathologic confirmation was obtained in 71% of children aged 10-14 years compared with 34% of children aged <2 years; however, severe extra-pulmonary TB was most common among children aged <2 years (41%). Classic TB symptoms should be considered when making a diagnosis; however, systematic symptoms among young children are also important. In high-burden settings, clinicians should have a low threshold to diagnose and treat children for TB across all ages, even in the context of a negative tuberculin skin test result and lack of micro-pathological confirmation.

Blood neutrophil counts in HIV-infected patients with pulmonary tuberculosis: association with sputum mycobacterial load.

Directory of Open Access Journals (Sweden)

Andrew D Kerkhoff

Full Text Available Increasing evidence suggests that neutrophils play a role in the host response to Mycobacterium tuberculosis. We determined whether neutrophil counts in peripheral blood are associated with tuberculosis (TB and with mycobacterial load in sputum in HIV-infected patients.Adults enrolling in an antiretroviral treatment (ART clinic in a Cape Town township were screened for TB regardless of symptoms. Paired sputum samples were examined using liquid culture, fluorescence microscopy, and the Xpert MTB/RIF assay. Absolute neutrophil counts (ANC were measured in blood samples. Of 602 HIV-infected patients screened, 523 produced one or more sputum samples and had complete results available for analysis. Among these 523 patients, the median CD4 count was 169×10(9/L (IQR, 96-232 and median ANC was 2.6×10(9/L (IQR, 1.9-3.6. Culture-positive pulmonary tuberculosis was diagnosed in 89 patients. Patients with TB had a median ANC of 3.4×10(9/L (IQR, 2.4-5.1 compared to 2.5×10(9/L (IQR, 1.8-3.4 among those who were culture negative (p7.5×10(9/L; p = 0.0005. Patients were then classified into four mutually exclusive groups with increasing sputum mycobacterial load as defined by the results of culture, Xpert MTB/RIF and sputum smear microscopy. Multivariable analyses demonstrated that increasing sputum mycobacterial load was positively associated with blood ANC ≥2.6×10(9/L and with neutrophilia.Increased blood neutrophil counts were independently associated with pulmonary TB and sputum mycobacterial burden in this HIV-infected patient group. This observation supports the growing body of literature regarding the potential role for neutrophils in the host response to TB.

Objective: To describe tomographic findings of lobar consolidation as early manifestation of primary pulmonary tuberculosis. Materials and methods: The present study was developed at Hospital Municipal Jesus, Rio de Janeiro, RJ, Brazil, in the period between 2002 and 2006, retrospectively evaluating tomographic findings in four children aged from 3 to 14 months with lobar consolidation as an early manifestation of primary pulmonary tuberculosis. Results: The most frequently found radiological pattern was lobar consolidation with calcifications, cavitation and intermingle necrotic areas, associated with bulging fissure. Signs of bronchogenic dissemination and lymph node enlargement were observed in all of the four children. Consolidation with a pseudotumor aspect and masslike effect was observed in one case. Conclusion: The cases included in the present study have demonstrated that primary pulmonary tuberculosis manifested as lobar consolidation presents typical tomographic images such as cavitation, hypodense areas and calcifications intermingled with consolidation. The association with lymph node enlargement with central necrosis and signs of bronchogenic dissemination reinforce the diagnosis of tuberculosis. (author)

Full Text Available The aim of this study was to analyse the clinical, epidemiological and bacteriological features present in 60 pulmonary tuberculosis patients who were also infected with human immunodeficiency virus (HIV and to compare these with 120 TB patients who were not infected with HIV. The patients with pulmonary tuberculosis and HIV coinfection were mostly male (p = 0.001, showed a higher frequency of weight loss >10 kilos (p <0.001, had a higher rate of non-reaction result to the tuberculin skin test (p <0.001, a higher frequency of negative sputum smear examination for acid-fast bacilli (p = 0.001 and negative sputum culture for Mycobacterium tuberculosis (p = 0.001. Treatment failure was more common in those who were HIV positive (p <0.000. No higher frequency of resistance to antituberculosis drugs was found to be associated with TB/HIV coinfection (p = 0.407. Association between extrapulmonary and pulmonary tuberculosis was more frequent in those seropositive to HIV than those without HIV virus, 30% and 1.6% respectively. These findings showed a predominance of atypical clinical laboratory features in co-infected patients, and suggest that health care personnel should consider the possibility this diagnosis.

The aim of our study was to identify the CT features helpful in the differential diagnosis of Iobar consolidation. We evaluated the CT findings in 52 consecutive patients with lobar consolidation which were proved to be pulmonary tuberculosis(n=24), malignant obstructive pneumonitis due to bronchogenic carcinoma(n=21), and lung abscess(n=7). We retrospectively reviewed CT scans with respect to 1) number of cavities or low attenuation area suggesting necrosis(we described these as cavity), 2) the contour of cavity, 3) enhancement of the cavity wall, 4) enhancement of pleura, 5) small nodules adjacent to the consolidation, 6) similar lesion in other location in lung, 7) air-bronchogram 8) mediastinal lymph node enlargement, and 9) extrapleural change. The helpful CT findings in the patients with pulmonary tuberculosis were multiple cavities(more than three; 79.2%), small nodules adjacent to the lobar consolidation(75.0%), similar lesion in another lobe or lung(91.7%), air-bronchogram(91.7%), and mediastinal lymph node enlargement(58.3%). Although extrapleural change had low sensitivity it was highly specific for pulmonary tuberculosis(sensitivity, 43.5%; specificity, 91.7%). Multiple cavities(61.9%) and mediastinal lymph node enlargement(52.4%) were common findings of malignant obstructive pneumonitis. In the patients with lung abscess, the common findings were small number of cavities(one or two, 85.7%) and air-bronchogram(85.7%). However, other findings of pulmonary tuberculosis were rarely seen in the patients with malignant obstructive pneumonitis or lung abscess. The CT findings of lobar consolidation may be used as useful adjuncts in the differential diagnosis of lobar consolidation.

Full Text Available Drug resistance in tuberculosis is a major public health challenge in developing countries. The limited data available on drug resistance in extra pulmonary tuberculosis stimulated us to design our study on anti-tuberculosis drug resistance pattern in cases of extra pulmonary tuberculosis in a tertiary referral hospital of North India. We performed Geno Type MTBDRplus assay in comparison with conventional drug susceptibility testing by proportion method to study the mutation patterns in rpoB, katG and inhA genes.A total of 510 extra pulmonary samples were included in this study. After the smear microscopy, all the specimens were subjected for culture on Lowenstein Jensen (LJ media. Phenotypic drug susceptibility testing (DST was performed on LJ media for all the MTB isolates and compared with the results of Geno Type MTBDRplus assay which was performed with the DNA isolated from the culture by conventional method.Of 510 specimens cultured, the total culture positivity obtained was 11.8% (60 encompassing 54 (10.6% Mycobacterium tuberculosis and 6 (1.2% non-tubercular mycobacteria (NTM. DST results by Geno Type MTBDRplus assay and solid culture methods were compared in 51 MTB isolates excluding the two Rif indeterminate and one invalid test. Geno Type MTBDRplus accurately identified 13 of 14 rifampicin-resistant strains, 14 of 15 isoniazid-resistant strains and 13 of 14 as multi drug resistant tuberculosis (MDR-TB in comparison with conventional method. Sensitivity and specificity were 92.86% and 97.30% respectively for detection of RIF resistance, 93.33% and 94.44% respectively for detection of INH resistance, 92.86% and 97.30% respectively for detection of MDR-TB, while the overall concordance of Geno Type MTBDRplus assay with conventional DST was 94.11%. The turn-around time for performing Geno Type MTBDRplus assay test was 48 hours.The problem of MDR in extra pulmonary tuberculosis (EPTB cannot be overlooked and due attention on patients

Objective: To evaluate three different enzyme immunoassays for serological diagnosis of pulmonary tuberculosis and to compare their diagnostic accuracy in different combinations. Subjects and Methods: Sera from patients suffering from pulmonary tuberculosis (n=94) with sputum positive for acid fast bacilli (AFB) and sera from control group of healthy individuals (n=90) with sputum negative for AFB were tested by Pathozyme-Myco G EIA, Pathozyme-TB Complex Plus EIA and Pathozyme Myco M EIA kits for the genus-specific IgG and IgM, and the species-specific IgG antibodies against antigens of Mycobacterium tuberculosis. Results: The detection of IgG against genus-specific antigens by Pathozyme-Myco G had a sensitivity of 46% and a specificity of 93%, of IgG against species-specific antigens by Pathozyme- TB Complex Plus had a sensitivity of 64% and specificity of 97% and of IgM against genus-specific antigens by Pathozyme Myco M had a sensitivity of 67% and specificity of 98%. When the results of these immunoassays were evaluated in combination, their sensitivity improved. Combination of genus-specific IgM and species-specific IgG yielded best results with a sensitivity of 87% and specificity of 93%. Conclusion: The sensitivity of serological diagnosis of tuberculosis is low, but it can be increased by utilizing a combination of several antigens. (author)

Chronic respiratory infectious diseases are causing high rates of morbidity and mortality worldwide. Tuberculosis, a major cause of chronic pulmonary infection, is currently responsible for approximately 1.5 million deaths per year. Although important advances in the fight against tuberculosis have been made, the progress towards eradication of this disease is being challenged by the dramatic increase in multidrug-resistant bacilli. Nontuberculous mycobacteria causing pulmonary disease and chronic pulmonary aspergillosis are emerging infectious diseases. In contrast to other infectious diseases, chronic respiratory infections share the trait of having highly variable treatment outcomes despite longstanding antimicrobial therapy. Recent scientific progress indicates that medicine is presently at a transition stage from programmatic to personalized management. We explain current state-of-the-art management concepts of chronic pulmonary infectious diseases as well as the underlying methods for therapeutic decisions and their implications for personalized medicine. Furthermore, we describe promising biomarkers and techniques with the potential to serve future individual treatment concepts in this field of difficult-to-treat patients. These include candidate markers to improve individual risk assessment for disease development, the design of tailor-made drug therapy regimens, and individualized biomarker-guided therapy duration to achieve relapse-free cure. In addition, the use of therapeutic drug monitoring to reach optimal drug dosing with the smallest rate of adverse events as well as candidate agents for future host-directed therapies are described. Taken together, personalized medicine will provide opportunities to substantially improve the management and treatment outcome of difficult-to-treat patients with chronic respiratory infections. © 2016 S.

The effectiveness and success of antituberculosis therapy is mainly measured by its ability to identify the organism in the sputum. In certain cases, available tuberculosis tests are not satisfactory and do not provide enough information on the effectiveness of antituberculosis therapy. Copper (Cu), zinc (Zn), and selenium (Se) are the essential elements that play a crucial role in the immune system. The serum levels of these elements vary in many diseases including tuberculosis. In this study, we investigate whether the serum levels of Cu, Zn, and Se change during antituberculosis therapy. We have included 22 pulmonary tuberculosis cases that were newly diagnosed with positive sputum and 18 healthy subjects. At the beginning and 2 mo after therapy, serum levels of Cu, Zn, and Se were measured by atomic absorption spectrometry. Despite Se and Cu levels not being affected during the treatment, we found that there was a significant increase in the levels of Zn and a decrease in the Cu/Zn ratio. Serum Zn levels and the Cu/Zn ratio could be used as a valuable laboratory tool for the clinicians to assess response to therapy or effectiveness of the ongoing antituberculosis therapy.

Background Phylogeographic composition of M. tuberculosis populations reveals associations between lineages and human populations that might have implications for the development of strategies to control the disease. In Latin America, lineage 4 or the Euro-American, is predominant with considerable variations among and within countries. In Colombia, although few studies from specific localities have revealed differences in M. tuberculosis populations, there are still areas of the country where this information is lacking, as is a comparison of Colombian isolates with those from the rest of the world. Principal Findings A total of 414 M. tuberculosis isolates from adult pulmonary tuberculosis cases from three Colombian states were studied. Isolates were genotyped using IS6110-restriction fragment length polymorphism (RFLP), spoligotyping, and 24-locus Mycobacterial interspersed repetitive units variable number tandem repeats (MIRU-VNTRs). SIT42 (LAM9) and SIT62 (H1) represented 53.3% of isolates, followed by 8.21% SIT50 (H3), 5.07% SIT53 (T1), and 3.14% SIT727 (H1). Composite spoligotyping and 24-locus MIRU- VNTR minimum spanning tree analysis suggest a recent expansion of SIT42 and SIT62 evolved originally from SIT53 (T1). The proportion of Haarlem sublineage (44.3%) was significantly higher than that in neighboring countries. Associations were found between M. tuberculosis MDR and SIT45 (H1), as well as HIV-positive serology with SIT727 (H1) and SIT53 (T1). Conclusions This study showed the population structure of M. tuberculosis in several regions from Colombia with a dominance of the LAM and Haarlem sublineages, particularly in two major urban settings (Medellín and Cali). Dominant spoligotypes were LAM9 (SIT 42) and Haarlem (SIT62). The proportion of the Haarlem sublineage was higher in Colombia compared to that in neighboring countries, suggesting particular conditions of co-evolution with the corresponding human population that favor the success of this

The objective of this study is to clarify clinical characteristics which differentiate bacteriologically positive pulmonary tuberculosis patients from negative ones in Mongolia. The subjects include 338 patients aged 16 years and older who had undergone bacteriological examinations. Of them, 107 patients (31.7%) were confirmed bacteriologically. The proportion of bacteriological positive results increased significantly among patients who had cavities in the roentgenographic examination, cough at diagnosis and the family history of tuberculosis. Addressing these clinical characteristics will contribute to raising not only the sensitivity of the sputum examination, but also the specificity of the roentgenographic examination in the diagnostic process of tuberculosis.

Diagnostic Yield of Bronchoalveolar Lavage Gene Xpert in Smear-Negative and Sputum-Scarce Pulmonary Tuberculosis

International Nuclear Information System (INIS)

Khalil, K. F.; Butt, T.

2015-01-01

Objective: To measure the diagnostic yield of Bronchoalveolar Lavage (BAL) gene Xpert (Xpert MTB/RIF assay), to detect Mycobacterium tuberculosis (MTB) and rifampicin resistance and compare it with that of mycobacterial cultures in a suspected case of pulmonary tuberculosis. Study Design: An analytical study. Place and Duration of Study: Department of Pulmonology, Fauji Foundation Hospital (FFH), Rawalpindi, from December 2012 to August 2013. Methodology: BAL specimens of 93 patients with suspected pulmonary tuberculosis with smear-negative or sputumscarce disease, who presented to the Department of Pulmonology, FFH, Rawalpindi were inducted. A smear-negative case was one in whom three consecutive early morning sputum samples did not reveal acid fast bacilli when examined by microscopy with Zeihl Nelson (ZN) stain. Patients who had sputum amount less than 1 ml were defined to have sputumscarce disease. The same was evaluated with ZN stain, gene Xpert and mycobacterial cultures. Sensitivity analysis was carried out using culture as the gold standard. Results: The frequency of positive mycobacterial cultures was 85 (91.4%). The sensitivity, specificity, positive predictive value and negative predictive values of BAL gene Xpert to detect Mycobacterium tuberculosis were 91.86%, 71.42%, 97.53% and 41.66% respectively. Xpert MTB/RIF assay had a sensitivity and specificity of 83.33% and 100% to detect rifampicin resistance. Conclusion: Bronchoalveolar lavage gene Xpert had a superior diagnostic yield in patients with either smear-negative or sputum-scarce pulmonary tuberculosis. Hence a positive Xpert MTB/RIF assay may be a useful adjunct to diagnosis and detection of MDR-TB in bronchoalveolar lavage specimens. (author)

Tuberculosis is a chronic pulmonary infectious disease that has affected one-third of the people in the world. It causes nine million new cases and two million deaths per year. Chest radiography associated with Ziehl-Neelsen acid-fast staining procedure significantly helps the diagnosis of pulmonary tuberculosis (PTB). Chest radiography can help the diagnosis of tuberculosis in patients with a negative smear sample result that is mainly diagnosed with delay. In this study, chest X-ray findings of PTB were compared in two groups of smear positive and smear negative patients. In this retrospective descriptive-analytical study, 376 patients who had been confirmed with PTB were referred to Birjand Health Care Center from 2001 to 2006. Out of the 376 patients, 100 patients with a positive smear based on WHO criteria were selected. In addition, among negative smear patients, 100 were selected in whom similar demographic characteristics with positive smear patients were seen. All of them had undergone chest radiographies that were then interpreted by two expert radiologists independently. Moreover, all patients’ sputa were examined by an expert laboratory technician at the reference laboratory of the health center. The obtained data were analyzed by means of frequency distribution table and descriptive statistics using SPSS (version 15) and Chi-square statistical test. Except reticulo-nodular infiltration, the relative frequency of other radiographic findings in positive smear patients were more than negative smear patients; and only differences in calcification variables, mediastinal widening, patchy infiltration and hilar adenopathy were statistically significant (P < 0.05). Based on the results of this study, although radiographic findings are not diagnostic in PTB, they are helpful if the assessment associates with the view of clinical manifestations and sputum smears

BCG protects toddlers during a tuberculosis outbreak.

Gaensbauer, J T

2009-05-01

In 2007, an outbreak of tuberculosis occurred in a toddler population attending two child care centres in Cork, Ireland. Of 268 children exposed, 18 were eventually diagnosed with active tuberculosis. We present the initial clinical and radiographic characteristics of the active disease group. Mantoux testing was positive in only 66% of cases. All cases were either pulmonary or involved hilar adenopathy on chest radiograph; there were no cases of disseminated disease or meningitis. 24% of the exposed children had been previously vaccinated with BCG, and no case of active disease was found in this group (p = 0.016), suggesting a profound protective effect of BCG in this population. Our experience provides evidence supporting a protective effect of BCG against pulmonary disease in young children.

Ocular tuberculosis: current perspectives

Full Text Available Faiz I Shakarchi1,21Ibn Al-Haetham Teaching Eye Hospital, 2Department of Opthalmology, Medical College, Al-Mustansiriya University, Baghdad, IraqAbstract: The World Health Organization currently estimates that nearly two billion people, or one-third of the world’s population, are infected by tuberculosis, and that roughly 10% of the infected people are symptomatic. Tuberculosis affects the lungs in 80% of patients, while in the remaining 20% the disease may affect other organs, including the eye. Uveitis can be seen concurrently with tuberculosis, but a direct association is difficult to prove. Ocular tuberculosis is usually not associated with clinical evidence of pulmonary tuberculosis, as up to 60% of extrapulmonary tuberculosis patients may not have pulmonary disease. The diagnosis of tuberculous uveitis is often problematic and in nearly all reported cases, the diagnosis was only presumptive. Tuberculous uveitis is a great mimicker of various uveitis entities and it can be considered in the differential diagnosis of any type of intraocular inflammation. It is still unknown if ocular manifestations result from a direct mycobacterium infection or hypersensitivity reaction and this is reflected on the management of tuberculous uveitis. Prevalence of tuberculosis as an etiology of uveitis may reach up to 10% in endemic areas. Tuberculous uveitis is a vision-threatening disease that inevitably leads to blindness if not properly diagnosed and treated. The aim of this review is to illustrate the various clinical features and management of presumed tuberculous uveitis. The current review focuses on the diagnostic criteria, significance of tuberculin skin test, and use of systemic corticosteroids in the management of tuberculous uveitis as recommended in recent publications.Keywords: tuberculosis, uveitis, choroiditis, tuberculin skin test

Full Text Available Common variable immunodeficiency (CVID usually manifests in the second or third decade of life with recurrent bacterial infections and hypoglobulinemia. Secondary renal amyloidosis with history of pulmonary tuberculosis is rare in CVID, although T cell dysfunction has been reported in few CVID patients. A 40-year-old male was admitted to our hospital with a 3-month history of recurrent respiratory infections and persistent pitting pedal edema. His past history revealed 3 to 5 episodes of recurrent respiratory tract infections and diarrhoea each year since last 20 years. He had been successfully treated for sputum positive pulmonary tuberculosis 8 years back. Laboratory studies disclosed high erythrocyte sedimentation rate (ESR, hypoalbuminemia and nephrotic range proteinuria. Serum immunoglobulin levels were low. CD4/CD8 ratio and CD3 level was normal. C3 and C4 complement levels were normal. Biopsy revealed amyloid A (AA positive secondary renal amyloidosis. Glomeruli showed variable widening of mesangial regions with deposition of periodic schiff stain (PAS pale positive of pink matrix showing apple green birefringence on Congo-red staining. Immunohistochemistry was AA stain positive. Immunofluorescence microscopy revealed no staining with anti-human IgG, IgM, IgA, C3, C1q, kappa and lambda light chains antisera. Patient was treated symptomatically for respiratory tract infection and was discharged with low dose angiotensin receptor blocker. An old treated tuberculosis and chronic inflammation due to recurrent respiratory tract infections were thought to be responsible for AA amyloidosis. Thus pulmonary tuberculosis should be considered in differential diagnosis of secondary causes of AA renal amyloidosis in patients of CVID especially in endemic settings.

Objective: To evaluate the clinical value of percutaneous injection of 70% ethanol in the treatment of multidrug resistant pulmonary tuberculosis. Methods: Percutaneous and transcatheter absolute ethanol, 70% ethanol, and 60% meglucamine diatrizoate(or distilled water) injection into the lung (25 cases) and the bronchi (25 cases) of healthy rabbits were performed, respectively.All specimens were studied with pathology. On the base of animals experiment, thirty-five patients with multi-drug resistant pulmonary tuberculosis were treated with percutaneous 70% ethanol injection. Every patient was treated by the same way for 1-3 times. Results: Pathological findings of the specimens of pulmonary tissue showed nonspecific inflammation, necrosis, and fibrosis. The chief pathological changes with percutaneous or transcatheter 70% ethanol injection were slighter than those with absolute ethanol injection. Pathological findings of the specimens of bronchi showed slight mucosal edema, nonspecific inflammation, and focal cytonecrosis. Recovery of the damaged bronchial mucosa occurred within 14-30 days after the treatment. All patients with multi-drug resistant pulmonary tuberculosis were followed up for 6 to 33 months. The sputum bacterial conversion to negative rate was 100% within 6 months after the treatment. Cavity closing, shrinking, and no changing rate were 47.1% (16/34), 50.0% (17/34), and 2.9% (1/34), respectively. Radiographic improvement rate was 94.3 % (33/35). No severe complications and adverse reactions occurred. Conclusion: Percutaneous 70% ethanol injection is safe, effective, and easy to perform in the treatment of multi-drug resistant pulmonary tuberculosis. (authors)

Tuberculosis is one of the oldest diseases and one third of the world's population is affected. Typical pattern (infiltration and or nodules with or without cavitations involving upper zone lung field) of pulmonary tuberculosis is the most common mode of radiological presentation in adults. There is a trend towards a relative increase in the unusual radiological presentations. This study was conducted to determine the frequency of atypical radiological trend of pulmonary tuberculosis in adults and elderly. Subjects and Methods: The objective of the study was to determine frequency of a typical radiological pattern of pulmonary tuberculosis in adults and elderly. It was a descriptive (case series) study and was conducted in the Department of Pulmonology, Nishtar Hospital Multan. The study duration was six months from 24 May 2006 to 23 November 2006. 300 patients presenting with pulmonary tuberculosis were selected. History and clinical examination was done. Relevant investigations and x-ray chest were carried out. Lesions like infiltration with or without cavitation were localized in upper, middle and lower zones. Groups of patients with their x-ray findings in different zones were made and analyzed accordingly, data collected were entered in specific proforma. Results: 205 (97.6%) adults and 85 (94.4%) elderly presented with cough while 205 (97.6%) adults and 75 (83.3%) elderly presented with fever. Out of 300 cases infiltration was found in 141 (46.19% vs 48.88%) young adult and elderly cases. There were 99 cases with nodule (35.71% vs 26.66%) and 60 cases had cavitation (18.09% vs 24.44%). Conclusion: There is a trend towards a relative increase in the frequency of unusual radiological presentations which is more common in elderly. (author)

Dissemination of the tubercle bacillus is of three types: bronchogenic, hematogenous, and lymphangitic. Bronchogenic dissemination occurs when exudate from a cavity or small area of caseation drains into a bronchus and is aspirated into previously uninfected areas either on the same or on the opposite side. This type of spreading occurs frequently after bleeding and when there is a cavity emptying into a bronchus. Hematogenous dissemination leads to miliary tuberculosis and to extrapulmonary lesions throughout the body. Acute massive hematogenous spread causes miliary tuberculosis, while chronic spread in smaller amounts usually results in the chronic extrapulmonary foci. Lymphangitic dissemination is common in primary infection. It is responsible for involvement with subsequent enlargement of hilar and mediastinal nodes that is often seen in children and in young black adults. The reaction to M. tuberculosis depends on the presence or absence of immunity to tuberculoprotein. In individuals having no tissue hypersensitivity or immunity, primary tuberculosis results. In those with immunity produced by previous infection or BCG vaccination, the reactivation (reinfection) disease may develop

Full Text Available Objective: To explore the serodiagnostic potential of the five recombinant Mycobacterium tuberculosis antigens CFP-10 (Rv3874, ESAT-6 (Rv3875, APA (Rv1860, PstS-1 (Rv0934, Ag85A (Rv3804c and their combination in a Cuban population with active pulmonary tuberculosis. Methods: The serodiagnostic potential of the recombinant antigens rESAT-6, rCFP-10, rAPA, rPstS-1 produced in Escherichia coli, rAg85A produced in Streptomyces lividans and the combination of the five proteins was evaluated by an indirect ELISA. Humoral immune response was analysed in a group of 140 patients with active pulmonary tuberculosis (smear-, Mantoux- and culture-positive and in a control group consisting of 34 bacillus CalmetteGuerin vaccinated, Mantoux-negative, healthy subjects. Results: With the exception of CFP-10, the use of the separate recombinant antigens or the antigenic cocktail in ELISA-based serodiagnosis resulted in a significant difference in the mean optical densitiy values between sera of patients and healthy subjects. The highest sensitivity of the assay using single antigens, being 58.57%, was achieved with rPstS-1 compared to 27.14% with rCFP-10, 31.65% with Ag85A, 42.86% with rAPA and 44.29% with rESAT-6. Single antigen ELISAs provided high specificity values ranging from 94.12% to 97.06%. A cocktail of the aforementioned antigens increased the sensitivity to 87.14% and the specificity to 97.06%. Conclusions: An ELISA using a multi-antigen mix containing recombinant immuno-dominant antigens of Mycobacterium tuberculosis, namely, rCFP-10, rESAT-6, rAPA, rPstS-1 and rAg85, increases the sensitivity and specificity compared with that using the single antigens and shows potential as a complementary tool for the diagnosis of active pulmonary tuberculosis in Cuba.

To analyse and compare high-resolution CT findings of pulmonary tuberculosis with consolidation and mycoplasma pneumonia. Twenty patients with pulmonary tuberculosis [confirmed by sputum culture (n=9) and bronchoscopic biopsy (n=11)] and airspace consolidation on high-resolution CT and 17 patients with mycoplasma pneumonia, confirmed by serologic test, were included in this study. High-resolution CT findings were analyzed in terms of ground-glass opacities, distribution of consolidation, type of nodules, cavities, interlobular septal thickening, bronchial dilatations, bronchial wall thickening and pleural effusion. In patients with tuberculosis, average age was 33.5 years (range, 20-67); in those with mycoplasma pneumonia it was 32.5 years (range, 17-74). Segmental and subsegmental distributions were most common in both diseases; the preferred site of consolidation was different, however; for tuberculosis it was the upper lobes (13 cases, 65%; bilateral involvement, 7 cases); for mycoplasma pneumonia it was the lower lobes (11 cases, 64.7%). Non-segmental (diffuse and random) distribution of ground-glass opacities were seen in two patients(11.8%) with mycoplasma pneumonia. Centrilobular nodules, branching linear opacities and alveolar nodules were not different in both diseases, but there were nodules above 10mm in 14 cases of tuberculosis and in only one case of mycoplasma pneumonia. Tree-in-bud appearances were seen in five cases of tuberculosis. Cavities without air-fluid level were noted in ten cases of tuberculosis. Other interlobular septal thickening, bronchial wall thickening, bronchial dilatation and pleural effusion were not different in both diseases. There was considerable overlap between high resolution CT findings of tuberculosis with airspace consolidation and those of mycoplasma pneumonia. The location of consolidation, type of nodules, and the presence of tree-in-bud appearance and cavities help in the differentiation of the two diseases, however.

To evaluate chest CT features of pulmonary tuberculosis mimicking lung malignancy. We retrospectively reviewed chest CT findings for 76 consecutive patients (21-84 years, average: 63 years; M : F = 30 : 46) who underwent an invasive diagnostic procedure under the suspicion of lung cancer and were pathologically diagnosed as pulmonary tuberculosis by bronchoscopic biopsy (n = 49), transthoracic needle biopsy (n = 17), and surgical resection (n = 10). We categorized the chest CT patterns of those lesions as follows: bronchial narrowing or obstruction without a central mass like lesion (pattern 1), central mass-like lesion with distal atelectasis or obstructive pneumonia (pattern 2), peripheral nodule or mass including mass-like consolidation (pattern 3), and cavitary lesion (pattern 4). CT findings were reviewed with respect to the patterns and the locations of the lesions, parenchymal abnormalities adjacent to the lesions, the size, the border and pattern of enhancement for the peripheral nodule or mass and the thickness of the cavitary wall in the cavitary lesion. We also evaluated the abnormalities regarding the lymph node and pleura. Pattern 1 was the most common finding (n = 34), followed by pattern 3 (n = 23), pattern 2 (n = 11) and finally, pattern 4 (n = 8). The most frequently involving site in pattern 1 and 2 was the right middle lobe (n = 14/45). However, in pattern 3 and 4, the superior segment of right lower lobe (n = 5/31) was most frequently involved. Ill-defined small nodules and/or larger confluent nodules were found in the adjacent lung and at the other segment of the lung in 31 patients (40.8%). Enlarged lymph nodes were most commonly detected in the right paratracheal area (n = 9/18). Pleural effusion was demonstrated in 10 patients. On the CT, pulmonary tuberculosis mimicking lung cancer most commonly presented with bronchial narrowing or obstruction without a central mass-like lesion, which resulted in distal atelectasis and obstructive

Tuberculosis (TB) is one of the oldest infectious diseases in the world and still affects humanity today. Since 1993, the World Health Organization (WHO) considers TB as a global emergency. The clinical history of the individual, the serum exams and particularly, the imaging examination of the thorax, are used for diagnostic confirmation and monitoring of disease. TB is a chronic disease that usually evolves with pulmonary sequelae that must be monitored. The exam of the image more precise to assess the radiological patterns found in these patients is high-resolution computed tomography (HRCT), which aids in medical diagnosis and permit the determination of the area affected by radiological abnormalities of pulmonary tuberculosis. The best known of such modifications by means of exams or more accurate techniques is of extreme importance. Therefore, this study aimed to show the quantification, performed by algorithms, of the areas affected by the radiological abnormalities of TB through the HRCT, and compared with serum exams. We studied 16 patients with confirmed diagnosis of TB. The serum exams evaluated included: hemoglobin, hematocrit, albumin, speed hemo sedimentation and C-reactive protein. With the values of serum exams we observed that patients have anemia, low albumin levels and inflammatory activity, corroborating imaging exams, which show severe impairment of lung area due to the inflammation caused by disease activity.

Materials and Methods. Quality of life assessment was performed in 95 patients with drug-resistant pulmonary tuberculosis who were treated in a specialized tuberculosis hospital at the penal colony. 53 patients of them were on palliative treatment and included into main observation group and comparison group consisted of 42 patients who received antimycobacterial chemotherapy in the maintenance phase of treatment. To determine the norms of quality studied indicators in our region, we have formed a control group consisted of 40 healthy volunteers. For quality of life assessment the questionnaire of the MOS SF-36 was used. Results. Increase the intensity of pain in palliative patients with drug-resistant pulmonary tuberculosis contributes physical functioning limitation. Acute emotional instability (depression, anxiety and negative emotions with limited social activity causes low self-esteem of mental state. Such changes ultimately result in inhibition of the viability and general health deterioration. For these patients particular attention should be paid to such scale of life quality assessment asPF,VT and MH as they were significantly lower compared with those drug-resistant pulmonary tuberculosis patients with antimycobacterial chemotherapy in maintenance phase of treatment. Conclusions. Drug-resistant tuberculosis in patients who are in palliative care leads to a drastic reduction of all quality of life parameters. Using the questionnaire of the MOS SF-36 for quality of life in palliative patients with drug-resistant pulmonary tuberculosis assessment is reasonable for a

The study was undertaken to reveal the clinical and epidemiological features of development diabetes mellitus (DM) and pulmonary tuberculosis (PT) in comorbidity. The material of the study was 143 case histories and outpatient cards of patients with DM and PT who were registered in 2001-2006. A total of 11,702 cases of tuberculosis were notified in 1999-2005. The significance ofa difference between the extensive indices was assessed by Student's test preceded by the Fisher angular transformation. Thus, the specific features of development of DM and PT are: 1) type 1 DM frequently occurs in youth while type 2 DM does at mature age; 2) tuberculosis in DM patients occurs at mature and old ages; 3) there is a male preponderance among patients with type 1 DM and a female predominance among those with type 2 DM; 4) comorbidity is more common in town-dwellers; 5) severe PT was prevalent in type 1 DM; mild PT is rarely observed in type 2 DM; 6) in comorbidity, fibro-cavernous, cirrhotic tuberculosis, caseous pneumonia, and tuberculoma are encountered by several times more frequently and focal tuberculosis and tuberculous pleurisy are less frequently in patients without DM.

Antimicrobial peptides for the treatment of pulmonary tuberculosis, allies or foes?

Tuberculosis is an ancient disease that has become a serious public health issue in recent years, although increasing incidence has been controlled, deaths caused by Mycobacterium tuberculosis have been accentuated due to the emerging of multi-drug resistant strains and the comorbidity with diabetes mellitus and HIV. This situation is threatening the goals of world health organization (WHO) to eradicate tuberculosis in 2035. WHO has called for the creation of new drugs as an alternative for the treatment of pulmonary tuberculosis, among the plausible molecules that can be used are the antimicrobial peptides (AMPs). These peptides have demonstrated remarkable efficacy to kill mycobacteria in vitro and in vivo in experimental models, nevertheless, these peptides not only have antimicrobial activity but also have a wide variety of functions such as angiogenesis, wound healing, immunomodulation and other well-described roles into the human physiology. Therapeutic strategies for tuberculosis using AMPs must be well thought prior to their clinical use; evaluating comorbidities, family history and risk factors to other diseases, since the wide function of AMPs, they could lead to collateral undesirable effects.

Extra-osseous uptake of bone-seeking radiopharmaceuticals has been reported at various sites and it is known to be induced by various causes. Diffuse pulmonary infection, such as tuberculosis, can be a cause of lung uptake of bone-scan agent. Here we report on a patient with non-tuberculosis mycobacterial infection (NTM) who demonstrated diffuse pulmonary uptake on Tc-99m MDP bone scan. After medical treatment for NTM, the patient's lung lesions improved. Estra skeletal lung Tc-99m MDP uptake on bone scan may suggest lung parenchymal damage associated with disease activity.

Objective: It is an investigation of the characteristic radiological findings of pulmonary tuberculosis in population of Nagquka, northern Tibet. Method: During July, 1996 to September, 1999, the initial chest film (CXR) of 117 cases of pulmonary tuberculosis from Nagquka, were compared with the CXR of 109 cases encountered in sea-side city Zhanjiang, with the same constituent ratio of age. According to the classification system for pulmonary tuberculosis of 1998, double-blinded investigation was made on the two groups and (x 2 test was applied for statistical analysis. Results: Higher rate (7.69%) of primary pulmonary tuberculosis with higher ratio of adult patients were revealed in Nagquka group, while high rate (93.6%) of secondary pulmonary tuberculosis was found in the control group. More cases (16.2%) presented segmental consolidation in Nagquka group than that in control group, while in most of cases (74.3%) of control group, small patchy lesions were the predominant pattern. In 31.6% cases of the research group, 4 or more lung fields were involved, while in the control group the ratio was 16.5%. More rare locations of the lesion, like inferior lung field were revealed in the research group, and the ratio of rare location was 12.8% in research group and 0.9% in the control group. The rate of cavity (11.97%) was not high in research group, but 32.1% in control group. Statistical significance was indicated (P 2 test. Conclusion: For the radiological manifestations of pulmonary tuberculosis, there are significant differences between the population of Nagquka and the sea-side city Zhanjiang

Herein, we present the case report of an adult male diabetic patient who had coinfection with Mycobacterium tuberculosis and mucormycosis, which otherwise is a rare clinical entity. Diabetes mellitus may predispose a patient to tuberculosis (TB) infection which further weakens immune system thus making him susceptible to other fungal or bacterial infections which may pose various treatment difficulties. Therefore, there is a need for mycological and bacteriological investigations in patients with pulmonary TB to rule out secondary coinfections thus contributing to better management.

Food security is the condition where the food fulfilment is managed well for the country till the individual. Indonesia is one of the country which has the commitment to create the food security becomes main priority. However, the food necessity becomes common thing means that it doesn’t care about nutrient standard and the health condition of family member, so in the fulfilment of food necessity also has to consider the disease suffered by the family member, one of them is pulmonary tuberculosa. From that reasons, this research is conducted to know the factors which influence on household food security status which suffered from pulmonary tuberculosis in the coastal area of Surabaya by using binary logistic regression method. The analysis result by using binary logistic regression shows that the variables wife latest education, house density and spacious house ventilation significantly affect on household food security status which suffered from pulmonary tuberculosis in the coastal area of Surabaya, where the wife education level is University/equivalent, the house density is eligible or 8 m2/person and spacious house ventilation 10% of the floor area has the opportunity to become food secure households amounted to 0.911089. While the chance of becoming food insecure households amounted to 0.088911. The model household food security status which suffered from pulmonary tuberculosis in the coastal area of Surabaya has been conformable, and the overall percentages of those classifications are at 71.8%.

DOTS Clinic with a DOTS-Plus pilot project for the management of multidrug-resistant tuberculosis (MDR-TB) in a high burden country. To determine the prevalence of tuberculosis (TB) infection and disease among pediatric household contacts of patients with pulmonary TB (PTB). Cross-sectional study. One hundred and fifty-three children aged 0-15 years in the households of 62 bacteriologically confirmed PTB patients, including 44 with MDR-TB, were studied. BCG scars were noted, and tuberculin skin test (TST), screening chest radiography, and sputum or gastric aspirate smear and culture for Mycobacterium tuberculosis in those with radiographic findings suggestive of PTB were done. For children in this study, the prevalences of latent TB infection (LTBI), radiographically diagnosed pulmonary TB, and bacillary pulmonary TB were 69.2%, 3.3%, and 0.65%, respectively. Only age > or = 5 years was found to be a significant predictor of LTBI (OR 3.17, 95%CI 1.43-7.01). Contact investigation for active case-finding and early treatment of TB in children from households of patients with active PTB is essential for TB control. Further study on a more precise definition of TB infection and strategies for control in this population will be pursued.

The aim of this work was to compare thin-section CT (TSCT) findings of drug-sensitive (DS) tuberculosis (TB), multidrug-resistant (MDR) TB, and nontuberculous mycobacterial (NTM) pulmonary disease in nonAIDS adults. During 2003, 216 (113 DS TB, 35 MDR TB, and 68 NTM) patients with smear-positive sputum for acid-fast bacilli (AFB), and who were subsequently confirmed to have mycobacterial pulmonary disease, underwent thoracic TSCT. The frequency of lung lesion patterns on TSCT and patients' demographic data were compared. The commonest TSCT findings were tree-in-bud opacities and nodules. On a per-person basis, significant differences were found in the frequency of multiple cavities and bronchiectasis (P<0.001, chi-square test and multiple logistic regression analysis). Multiple cavities were more frequent in MDR TB than in the other two groups and extensive bronchiectasis in NTM disease (multiple logistic regression analysis). Patients with MDR TB were younger than those with DS TB or NTM disease (P<0.001, multiple logistic regression analysis). Previous tuberculosis treatment history was significantly more frequent in patients with MDR TB or NTM disease (P<0.001, chi-square test and multiple logistic regression analysis). In patients with positive sputum AFB, multiple cavities, young age, and previous tuberculosis treatment history imply MDR TB, whereas extensive bronchiectasis, old age, and previous tuberculosis treatment history NTM disease.

Full Text Available Primary involvement of liver in tuberculosis is a rare entity. It is difficult to diagnose in absence of previous history of tuberculosis or concurrent pulmonary involvement. It is usually misdiagnosed as neoplastic liver lesion, which misdirects the treatment protocol and delays proper treatment. Here we are presenting a case of 36-year-old male patient with vague right upper quadrant abdominal pain. All the laboratory values were within normal limits. Radiological investigations were in favor of biliary cystadenoma but final diagnosis was primary focal involvement of liver in tuberculosis which was histopathologically proven to be tuberculous granulomas on biopsy of the resected mass.

Background Diabetes and TB are associated, and diabetes is increasingly common in low-income countries where tuberculosis (TB) is highly endemic. However, the role of diabetes for TB has not been assessed in populations where HIV is prevalent. Methods A case-control study was conducted in an urban...... population in Tanzania among culture-confirmed pulmonary TB patients and non-TB neighbourhood controls. Participants were tested for diabetes according to WHO guidelines and serum concentrations of acute phase reactants were measured. The association between diabetes and TB, and the role of HIV as an effect...

The IGRA-ELISA and T-SPOT.TB are widely used in China. The aim of the study was to evaluate the performance of the two assays in diagnosis Mycobacterium tuberculosis infection. Of the 3727 patients in the study, 204 underwent testing using both the T-SPOT.TB and IGRA-ELISA, 1794 were tested using the T-SPOT.TB only, and 1729 were tested using the IGRA-ELISA only. The positive rate and consistency of the two assays were analyzed, and their sensitivity and specificity for diagnosing active tuberculosis were compared. There were no significant differences in the positive rate between the T-SPOT.TB test (25.8%) and IGRA-ELISA (28.6%), p = .065. The two assays were highly consistent, with a kappa value of 0.852 (p SPOT.TB test were 82.9% (107/129) and 78.6% (1309/1665), respectively, and those of IGRA-ELISA were 81.7% (94/115) and 75.2% (1214/1614), respectively. There were no significant differences in sensitivity (p > .05), but the specificity of the T-SPOT.TB test was slightly higher than that of IGRA-ELISA (p = .023). Both in terms of diagnosing M. tuberculosis infection and ruling out active tuberculosis, the performance of the IGRA-ELISA-a simple, almost labor-free assay that allows simultaneous processing of a very large number of samples-was well-matched with that of T-SPOT.TB test. However, IGRAs cannot be used as the only test to diagnose active tuberculosis. Copyright © 2018 Elsevier B.V. All rights reserved.

Isoniazid mono-resistance (IMR) is the most common form of mono-resistance; its world prevalence is estimated to range between 0.0 to 9.5% globally. There is no consensus on how these patients should be treated. To describe the impact of IMR tuberculosis (TB) on treatment outcome and survival among pulmonary TB patients treated under programmatic conditions in Orizaba, Veracruz, Mexico. We conducted a prospective cohort study of pulmonary TB patients in Southern Mexico. From 1995 to 2010 patients with acid-fast bacilli or culture proven Mycobacterium tuberculosis in sputum samples underwent epidemiological, clinical and microbiological evaluation. We included patients who harbored isoniazid mono-resistant (IMR) strains and patients with strains susceptible to isoniazid, rifampicin, ethambutol and streptomycin. All patients were treated following Mexican TB Program guidelines. We performed annual follow-up to ascertain treatment outcome, recurrence, relapse and mortality. Between 1995 and 2010 1,243 patients with pulmonary TB were recruited; 902/1,243 (72.57%) had drug susceptibility testing; 716 (79.38%) harbored pan-susceptible and 88 (9.75%) IMR strains. Having any contact with a person with TB (adjusted odds ratio (aOR)) 1.85, 95% Confidence interval (CI) 1.15-2.96) and homelessness (adjusted odds ratio (aOR) 2.76, 95% CI 1.08-6.99) were associated with IMR. IMR patients had a higher probability of failure (adjusted hazard ratio (HR) 12.35, 95% CI 3.38-45.15) and death due to TB among HIV negative patients (aHR 3.30. 95% CI 1.00-10.84). All the models were adjusted for socio-demographic and clinical variables. The results from our study provide evidence that the standardized treatment schedule with first line drugs in new and previously treated cases with pulmonary TB and IMR produces a high frequency of treatment failure and death due to tuberculosis. We recommend re-evaluating the optimal schedule for patients harboring IMR. It is necessary to strengthen

Full Text Available Objective/Background: The aim of this study was to analyze the detection of nontuberculous mycobacterial (NTM species derived from sputum specimens of pulmonary tuberculosis (TB suspects. Increasing prevalence and incidence of pulmonary infection by NTM species have widely been reported in several countries with geographical variation. Materials and Methods: Between January 2014 and September 2015, sputum specimens from chronic pulmonary TB suspect patients were analyzed. Laboratory examination of mycobacteria was conducted in the TB laboratory, Department of Clinical Microbiology, Dr. Soetomo Hospital, Surabaya. Detection and identification of mycobacteria were performed by the standard culture method using the BACTEC MGIT 960 system (BD and Lowenstein–Jensen medium. Identification of positive Mycobacterium tuberculosis complex (MTBC was based on positive acid-fast bacilli microscopic smear, positive niacin accumulation, and positive TB Ag MPT 64 test results (SD Bioline. If the growth of positive cultures and acid-fast bacilli microscopic smear was positive, but niacin accumulation and TB Ag MPT 64 (SD Bioline results were negative, then the isolates were categorized as NTM species. MTBC isolates were also tested for their sensitivity toward first-line anti-TB drugs, using isoniazid, rifampin, ethambutol, and streptomycin. Results: From 2440 sputum specimens of pulmonary TB suspect patients, 459 isolates (18.81% were detected as MTBC and 141 (5.78% as NTM species. Conclusion: From the analyzed sputum specimens, 18.81% were detected as MTBC and 5.78% as NTM species. Each pulmonary TB suspect patient needed clinical settings to suspect causative agents of MTBC and/or NTM species; clinicians have to understand the local epidemiological data for the evaluation of causes of lung infection to determine appropriate therapy.

Extensively drug-resistant tuberculosis (XDR-TB) is an emerging global health risk. We present the first case report of XDR-TB in Singapore. A 41-year-old Indonesian lady with previously treated pulmonary tuberculosis presented with chronic cough. Her sputum was strongly acid-fast bacilli positive and grew Mycobacterium tuberculosis complex resistant to first and second-line TB medications. She received 5 months of intensive multidrug treatment without sputum smear conversion. She then underwent resection of the diseased lung. The total cost incurred amounted to over S$100,000. She achieved sputum smear/culture conversion post-surgery, but will require further medical therapy for at least 18 months. XDRTB is poorly responsive to therapy and extremely expensive to manage. Its prevention by strict compliance to therapy is paramount.

Pathology and immune reactivity: understanding multidimensionality in pulmonary tuberculosis.

Heightened morbidity and mortality in pulmonary tuberculosis (TB) are consequences of complex disease processes triggered by the causative agent, Mycobacterium tuberculosis (Mtb). Mtb modulates inflammation at distinct stages of its intracellular life. Recognition and phagocytosis, replication in phagosomes and cytosol escape induce tightly regulated release of cytokines [including interleukin (IL)-1, tumor necrosis factor (TNF), IL-10], chemokines, lipid mediators, and type I interferons (IFN-I). Mtb occupies various lung lesions at sites of pathology. Bacteria are barely detectable at foci of lipid pneumonia or in perivascular/bronchiolar cuffs. However, abundant organisms are evident in caseating granulomas and at the cavity wall. Such lesions follow polar trajectories towards fibrosis, encapsulation and mineralization or liquefaction, extensive matrix destruction, and tissue injury. The outcome is determined by immune factors acting in concert. Gradients of cytokines and chemokines (CCR2, CXCR2, CXCR3/CXCR5 agonists; TNF/IL-10, IL-1/IFN-I), expression of activation/death markers on immune cells (TNF receptor 1, PD-1, IL-27 receptor) or abundance of enzymes [arginase-1, matrix metalloprotease (MMP)-1, MMP-8, MMP-9] drive genesis and progression of lesions. Distinct lesions coexist such that inflammation in TB encompasses a spectrum of tissue changes. A better understanding of the multidimensionality of immunopathology in TB will inform novel therapies against this pulmonary disease.

Extra-osseous uptake of bone-seeking radiopharmaceuticals has been reported at various sites and it is known to be induced by various causes. Diffuse pulmonary infection, such as tuberculosis, can be a cause of lung uptake of bone-scan agent. Here we report on a patient with non-tuberculosis mycobacterial infection (NTM) who demonstrated diffuse pulmonary uptake on Tc-99m MDP bone scan. After medical treatment for NTM, the patient's lung lesions improved. Estra skeletal lung Tc-99m MDP uptake on bone scan may suggest lung parenchymal damage associated with disease activity.

The role of tuberculosis as a public health care priority and the availability of diagnostic tools to evaluate functional status (spirometry, plethysmography, and DLCO determination), arterial blood gases, capacity to perform exercise, lesions (chest X-ray and CT), and quality of life justify the effort to consider what needs to be done when patients have completed their treatment. To our knowledge, no review has ever evaluated this topic in a comprehensive manner. Our objective was to review the available evidence on this topic and draw conclusions regarding the future role of the "post-tuberculosis treatment" phase, which will potentially affect several million cases every year. We carried out a non-systematic literature review based on a PubMed search using specific keywords (various combinations of the terms "tuberculosis", "rehabilitation", "multidrug-resistant tuberculosis", "pulmonary disease", "obstructive lung disease", and "lung volume measurements"). The reference lists of the most important studies were retrieved in order to improve the sensitivity of the search. Manuscripts written in English, Spanish, and Russian were selected. The main areas of interest were tuberculosis sequelae following tuberculosis diagnosis and treatment; "destroyed lung"; functional evaluation of sequelae; pulmonary rehabilitation interventions (physiotherapy, long-term oxygen therapy, and ventilation); and multidrug-resistant tuberculosis.The evidence found suggests that tuberculosis is definitively responsible for functional sequelae, primarily causing an obstructive pattern on spirometry (but also restrictive and mixed patterns), and that there is a rationale for pulmonary rehabilitation. We also provide a list of variables that should be discussed in future studies on pulmonary rehabilitation in patients with post-tuberculosis sequelae.

Full Text Available Background: Inadequate diagnostic processes and human resources in laboratories contribute to a high burden of tuberculosis (TB in low- and middle-income countries. Direct smear microscopy is relied on for TB diagnosis; however, sensitivity rates vary. To improve sensitivity of direct microscopy, the researchers employed several approaches, including sputum digestion and concentration of acid-fast bacilli (AFB, a technique which uses commercial bleach. Objectives: This study compared methods used to diagnose active Mycobacterium tuberculosis infections. Methods: Three sputum specimens were collected from each of 340 participants in Abuja, Nigeria, over two consecutive days. Direct microscopy was performed on all specimens; following microscopy, one specimen from each patient was selected randomly for bleach sedimentation and one for Lowenstein-Jensen culture. Results: Direct microscopy produced 28.8% AFB-positive results, whilst bleach sedimentation resulted in 30.3%. When compared with the cultures, 26.5% were AFB true positive using direct microscopy and 27.1% using bleach sedimentation. Whilst the specificity rate between these two methods was not statistically significant (P = 0.548, the sensitivity rate was significant (P = 0.004. Conclusion: Based on these results, bleach increases the sensitivity of microscopy compared with direct smear and has similar specificity. When diagnosing new cases of pulmonary TB, one bleach-digested smear is as sensitive as three direct smears, reducing waiting times for patients and ensuring the safety of laboratory technicians.

To compare the effectiveness of embolization of the bronchial artery embolization for the management of hemoptysis in pulmonary tuberculosis cases with the severity of lung parenchymal injury and pleural infiltration, as seen on plain chest radiographs, and with the findings of angiography of the branchial artery. Among 265 patients with hemoptysis due to pulmonary tuberculosis, the findings of plain chest radiography and angiography of the bronchial artery were comparatively analyzed in the 206 for whom the results of follow up were available. The chest radiographin findings were classified as follows: Type I refers to simple pulmonary tuberculosis; Type II includes cases in which pulmonary tuberculosis is complicated by bronchiectasis, aspergillosis, or cavitation; Type III si either Types I or II acompainted by pleural in filtrates limited to the lung apex, and Type IV includes cases in which pleural infiltrates have extended beyond the apex in the whole the lung. Bronchial angiographic findings were divided into four groups: Group I consists of cases which show abnormalities of only the bronchial artery; Group II includes those in which abnormalities are seen in the bronchial artery and either the internal mammary or an intercostal artery; Group III comprises cases which belong to Group I or II and which a bronch of the subclavian artery is abnormal, and Group IV includes those in which abnormalities occur in at least two branches of the subclavian artery, or there is direct visualization of hypervascularity of this vessel. The initial post-embolic hemostatic effect and the results of follow up were studied over a six-month period. As compared with simple pulmonary tuberculosis (Type I), we found that as the severity of pleural infiltration and complications revealed by plain chest radiographs increased (Type II, III, IV), so did the severity of the manifestation of systemic collateral arteries other than the bronchial artery, as depicted by increased on

Evaluating outcomes after tuberculosis (TB) treatment can help identify the primary reasons for treatment success or failure. However, Yemen has a treatment success rate that remains below the World Health Organization's target. This study aimed to identify factors that were associated with unsuccessful treatment and prolonged treatment (>1 year). Newly diagnosed cases of smear-positive pulmonary TB were prospectively followed at two centers (Taiz and Alhodidah, Yemen) between April 2014 and March 2015. Standardized forms were used to obtain information from the patients regarding their socio-demographic and clinical characteristics, treatment duration, and TB-related information. Multivariate logistic regression analyses were performed to identify factors that were associated with unsuccessful treatment and prolonged treatment (>1 year). The study included data from 273 cases of newly diagnosed TB, with treatment being successful in 227 cases (83.1%) and unsuccessful in 46 cases (16.9%). Among the 46 patients with unsuccessful treatment, 29 patients (10.6%) stopped treatment, 6 patients (2.2%) transferred to another facility, 6 patients (2.2%) experienced treatment failure, and 5 patients (1.8%) died. The multivariate logistic regression analyses revealed that unsuccessful treatment was associated with female sex, illiterate status, and the presence of comorbidities. Prolonged treatment durations were associated with living in a rural area, smoking, chewing khat, a cough that lasted for >3 weeks at the beginning of treatment, and bilateral cavities during radiography. These results confirm that the treatment success rate in Yemen is lower than the World Health Organization's target for smear-positive pulmonary tuberculosis. Targeting the risk factors that we identified may help improve treatment outcomes. Furthermore, it may not be prudent to re-treat patients using first-line TB drugs after an initial treatment failure.

Although pulmonary epithelial cells are integral to innate and adaptive immune responses during Mycobacterium tuberculosis infection, global transcriptomic changes in these cells remain largely unknown. Changes in gene expression induced in pulmonary epithelial cells infected with M. tuberculosis F15/LAM4/KZN, F11, F28, Beijing and Unique genotypes were investigated by RNA sequencing (RNA-Seq). The Illumina HiSeq 2000 platform generated 50 bp reads that were mapped to the human genome (Hg19) using Tophat (2.0.10). Differential gene expression induced by the different strains in infected relative to the uninfected cells was quantified and compared using Cufflinks (2.1.0) and MeV (4.0.9), respectively. Gene expression varied among the strains with the total number of genes as follows: F15/LAM4/KZN (1187), Beijing (1252), F11 (1639), F28 (870), Unique (886) and H37Rv (1179). A subset of 292 genes was commonly induced by all strains, where 52 genes were down-regulated while 240 genes were up-regulated. Differentially expressed genes were compared among the strains and the number of induced strain-specific gene signatures were as follows: F15/LAM4/KZN (138), Beijing (52), F11 (255), F28 (55), Unique (186) and H37Rv (125). Strain-specific molecular gene signatures associated with functional pathways were observed only for the Unique and H37Rv strains while certain biological functions may be associated with other strain signatures. This study demonstrated that strains of M. tuberculosis induce differential gene expression and strain-specific molecular signatures in pulmonary epithelial cells. Specific signatures induced by clinical strains of M. tuberculosis can be further explored for novel host-associated biomarkers and adjunctive immunotherapies. Copyright © 2016 Elsevier Ltd.

To elucidate the differences in affected lung segments between patients with pulmonary M. kansasii infection and those with M. tuberculosis infection in the initial stage of disease, we examined chest radiography images and CT scans. The initial stage of disease was defined as the period when less than one-sixth of the total lung area was affected by the infection, as visualized on chest radiography and CT. One hundred eighty-four patients were diagnosed with M.kansasii infection between 1996 and 2010 and 835 patients, with M.tuberculosis infection between 2008 and 2009 at our hospital. The diagnosis was made on the basis of the results of sputum culture and/or bronchial washing. After excluding the patients with underlying lung diseases such as chronic pulmonary emphysema, interstitial pneumonia, and old pulmonary tuberculosis as well as those in advanced stages, 24 patients with M. kansasii infection and 62 patients with M. tuberculosis infection were included in this study. The affected segments of the lungs and the rates of cavity development were determined by using CT scans. In patients with M.kansasii, 17 had an infected right lung, while 7 had an infected left lung. Additionally, in patients with M.tuberculosis, 58 had an infected right lung, 3 had an infected left lung, and 1 had a bilateral infection. In patients infected with M. kansasii, the upper lobes were affected in 22 cases and the lower lobes in 3 cases. In patients infected with M. tuberculosis, the upper, middle, and lower lobes and the lingular segment were affected in 41, 8, 24, and 1 cases, respectively. Upper lobe lesions were seen more frequently in patients with M. kansasii infection than in those with M. tuberculosis infection (p formation was identified more frequently in patients infected with M. kansasii (91.7%) than in those infected with M. tuberculosis (32.3%) (p < 0.001). Cavitary lesions were more frequently localized to the apical, posterior, and apico-posterior regions (S1, S2

Methods: A cross sectional study was carried out from February, 2012 to June, 2013 and 97 (76 sputum and 21 fine needle aspirate samples were taken from tuberculosis diagnosed patients at Dilla University Referral Hospital and other private clinics. Culturing, region of difference (RD9 deletion typing and spoligotyping techniques were employed to isolate M. tuberculosis strains. Results: Growth of mycobacteria was observed in 35.1% (34/97. Speciation of isolates showed that 91.2% (31/34 of the isolates were M. tuberculosis. Further characterization led to the identification of 23 different spoligotype patterns of M. tuberculosis of which 61% and 39% displayed unique and cluster patterns, respectively. The most dominant shared type was spoligotype international type 53. Of the 23 strains, 12 have not been registered in the international spoligotyping database (SpolDB4. Seventy one percent of the strains belonged to the Euro-American lineage. Conclusions: This study revealed the existence of both genetically diverse and clustered M. tuberculosis strains from tuberculosis patients in the area, suggesting reactivation of infection and recent transmission, respectively. Molecular epidemiology of M. tuberculosis should be done nationwide in order to set appropriate control measures.

Tuberculosis (TB) continues to be a major public health problem. An estimated one-third of the world's population is infected with Mycobacterium tuberculosis (Mtb) but remains asymptomatic (latent TB) and only 5% to 10% of these latent individuals will develop active pulmonary TB. Factors affecting the balance between latent and active TB are mostly unknown, even if host genome has been shown to contribute to the outcome of Mtb response. Acute inflammation and Th1 response are important in the early clearance of the bacteria as it was emphasized by the association between immune genes (i.e.: HLA, IFNG, TNF, NRPAM1, IL10) variants and the development of active pulmonary TB. Recently, the role of the inflammasome in experimental TB has been demonstrated, however, to our knowledge, no data still exist about the contribution of inflammasome genetics to Mtb susceptibility and/or to the development of active TB. For this reason, selected polymorphisms in inflammasome genes were analysed in a case/control cohort of individuals with active pulmonary TB from an endemic area of Brazil Amazon. Our data evidence the novel association between polymorphisms in NLRP3-inflammasome encoding genes and active pulmonary TB, and replicated the association between P2X7 and TB observed in other populations. These results emphasize the role of NLRP3-inflammasome also in human TB, and contribute to our knowledge about pathways involved in the development of active TB, even if deeper investigation are needed to fully elucidate the role of the complex in Mtb infection.

Full Text Available Aims: To describe the number, types and reasons of consultations amongst patients of pulmonary tuberculosis from an urban area. Settings and Design Cross sectional study was conducted amongst new patients of pulmonary tuberculosis initiated on DOTS at District Tuberculosis Centre (DTC, Yavatmal from January to June 2006. Material and Methods: The data regarding consultations were collected along a time line. The reasons for consultations were studied by in-depth interviews. Statistical analysis: Logistic regression analysis and transcripts of interviews. Results and Conclusions A total of 55 patients were studied in whom median duration between first consultation to treatment initiation was 15 days. A majority of cases (87.27% had first consulted a private practitioner. A total of 32 patients reported more than two consultations and 19 had consulted more than two private health service providers. Amongst the movements between consultations, a majority were from private to government. Only four patients had come to DTC without any prior consultation. Many patients came to government health service provider on their own when the symptomatic treatment prescribed by the private practitioners did not relieve their symptoms.

Full Text Available OBJECTIVE The aim of the present study is to record the clinical, radiological profile of pulmonary and extra pulmonary tuberculosis (EPTB in HIV positive patients. To win the battle against AIDS we have to fight against TB. Unlike HIV/AIDS, TB is completely curable in the vast majority of cases. MATERIALS AND METHODS This prospective study was conducted in the department of pulmonary medicine, Gadag institute of medical sciences, Gadag. All newly diagnosed HIV patients during the study period were included and screened for TB. HIV infection was confirmed by enzyme linked immunosorbent assay using two different antigens and a rapid test as recommended by NACO. RESULTS Among 370 newly diagnosed HIV positive patients, 113(30.54% patients were diagnosed to have TB. Most common affected age group was 31-40years with a mean age of 38.08 years. Unprotected heterosexual contact was the most common mode of HIV transmission. Fever, weight loss and cough were the commonest symptoms at presentation. Pulmonary TB was diagnosed in 85(22.97% patients, EPTB in 21(5.67% and disseminated TB in 7(1.8% patients. Among the EPTB patients, 2(9.5% patients had extra thoracic lymphadenopathy. Cervical lymph node was the commonest lymph node involved. 14(66.66% patients had pleural effusion, 3(14.28% had abdominal TB, 1(4.76% had tubercular meningitis and 1(4.76% patient had TB testis. CONCLUSION The prevalence of HIV–TB co-infection was high. Moreover, HIV positive patients need early diagnosis and treatment of active TB. However large sample size prospective studies are needed to correlate the clinical and CD4 count with the occurrence of different types of tuberculosis.

Full Text Available Abdominal Tuberculosis (TB most commonly affects ileo-caecal region. Isolated stomach involvement by TB, without pulmonary infection is rare. Clinical presentation of Stomach TB may be non-specific, radiological findings non-contributory and superficial endoscopic biopsies may not be able to settle the diagnosis. Many cases are diagnosed only after histopathological examination of surgical specimens. High degree of suspicion is needed for early diagnosis of gastric tuberculosis, if unnecessary surgical interventions are to be avoided. A young patient who was being treated as a case of chronic peptic ulcer for one year was referred for treatment of gastric outlet obstruction. Histopathological examination of gastrectomy specimen of the patient showed multiple caseating granulomas characteristic of tuberculosis and presence of acid-fast bacilli on Fite-Faraco staining, with no evidence of tuberculosis at pulmonary or other body sites. This case of isolated gastric TB is reported for its rarity.

In Poland the incidence rate of tuberculosis is higher than the average for countries of the European Union, Norway or Iceland. On the other hand, occupational tuberculosis is still rarely recognized in our country. In this paper we present the first in Poland--to our best knowledge--case of pulmonary manifestation of this disease acquired at work in a funeral director. The recognition of the occupational etiology of the discussed illness gave rise to an array of diagnostic problems and became feasible after a thorough analysis of the patient's history and literature data, which allowed finding the relationship between infection and performed job. We speculated that the transfer of the dead body and handling of cadavers may expel residual air from the lungs of the deceased. Although tuberculosis occurs frequently in the general population, the recognition of work-related cases of this disease is still rare, especially among funeral directors.

The purpose of this study was to clarify the points to be considered when QuantiFERON-TB second generation (QFT-2G) tests are used in the contacts examination by public health center. We analyzed the results of contacts examination on 43 workplace colleagues (39 y/o and younger) of a pulmonary tuberculosis patient (bII2, Gaffky 9, cough for 1.5 months). After two months of the last contact with the index case, tuberculin skin tests, QFT-2G tests and chest X-rays were undertaken. After 6 months, chest X-rays were taken, and after 9 months, QFT-2G tests and chest CT scans were also undertaken. The tuberculin skin tests after two months showed a bimodal distribution, and 10 were QFT-2G positive and 2 showed doubtful reaction. The latter 12 persons underwent chemoprophylaxis. After 6 months, however, out of 31 QFT-2G negative persons, 2 developed pulmonary tuberculosis. Moreover, after 9 months, chest CT scans revealed 5 pulmonary tuberculosis patients. Three out of 7 new patients showed positive or doubtful reactions in QFT-2G tests undertaken after 9 months. The sensitivity of QFT-2G tests is reported to be 80 to 90%, and the possibility of false negative is not negligible. We propose measures for public health center to conduct the contacts examination as follows; In case of high QFT-2G positive (including doubtful reaction) rate and/or a bimodal distribution of tuberculin skin test result, many infected persons are likely to be included in the group; and the following measures are recommended; Necessity of chemoprophylaxis should be judged considering both tuberculin skin test results and the situation of contact with the index case, and not only by QFT-2G test results. QFT-2G negative persons also need to be followed with chest X-rays. (author)

Background: The homeless are at very high risk of suffering tuberculosis (TB). The aims of this study were to determine the prevalence and risk factors for tuberculosis infection and disease among the homeless in Barcelona and to evaluate the roles of case finding and contact investigation. Methods: Observational prevalence study carried out between 1997 and 1998. Participants: 447 homeless patients (394 men and 53 women) were evaluated before admission to shelters and free-meal services. At the same time, 48 co-residents with smear-positive TB patients in 2 long-term shelters were evaluated too. A chest X-ray and Tuberculin Skin Test were performed on all subjects. Sputum smears were processed by the Ziehl-Neelsen and Loewenstein-Jensen procedures in patients with radiographic findings consistent with pulmonary TB. Results: Of the 447 homeless examined, 335 (75%) were infected with Mycobacterium tuberculosis. Active pulmonary TB was diagnosed in five persons (1.11%), and 62 (13.8%) had radiographic evidence of inactive pulmonary TB. Tuberculosis infection was associated with age and smoking, but not with sex or alcohol abuse. No significant differences in infection rates were found between the main group and 48 homeless co-residents of smear-positive subjects. Only 16.9% of the homeless with active TB in Barcelona in the same period were diagnosed through active case-finding, the remainder being mainly detected in hospitals (69.8%) and other several centres (13.3%). Conclusions: Homeless individuals have a very high risk of TB infection and disease and contact investigation requires specific methods for them. Programmes of screening and supervised treatment should be ensured in this group

Full Text Available Mycobacterium tuberculosis: is most commonly associated with pulmonary infection. However, tuberculosis (TB can also affect the eye. TB can affect nearly any tissue in the eye, and a high index of suspicion is required for accurate diagnosis, as many of the intraocular manifestations of TB can mimic other, more common diseases. Correct diagnosis is critical because systemic anti-tuberculosis treatment may be required, and vision loss or even loss of the affected eye can occur without proper treatment. Thus, it is important for ophthalmologists and infectious disease specialists to work together to accurately diagnose and treat intraocular TB. This article reports the various known presentations of intraocular TB and reviews important elements of diagnosis and treatment.

Highlights: • Digital tomosynthesis and dual energy subtraction digital radiography are modifications of digital radiography. • These modalities perform better than digital radiography in detection of parenchymal lesions in active pulmonary tuberculosis. • Digital tomosynthesis has a sensitivity of 100% in detection of cavities. • Centrilobular nodules seen on CT in active pulmonary tuberculosis, were also demonstrated on digital tomosynthesis in our study. • Digital tomosynthesis can be used for diagnosis and follow up of patients in pulmonary tuberculosis, thereby reducing the number of CT examinations. - Abstract: Objective: To assess the role of digital tomosynthesis (DTS) and dual energy subtraction digital radiography (DES-DR) in detection of parenchymal lesions in active pulmonary tuberculosis (TB) and to compare them with digital radiography (DR). Materials and methods: This prospective study was approved by our institutional review committee. DTS and DES-DR were performed in 62 patients with active pulmonary TB within one week of multidetector computed tomography (MDCT) study. Findings of active pulmonary TB, that is consolidation, cavitation and nodules were noted on digital radiography (DR), DTS and DES-DR in all patients. Sensitivity, specificity, positive and negative predictive values of all 3 modalities was calculated with MDCT as reference standard. In addition presence of centrilobular nodules was also noted on DTS. Results: Our study comprised of 62 patients (33 males, 29 females with age range 18–82 years). Sensitivity and specificity of DTS for detection of nodules and cavitation was better than DR and DES-DR. Sensitivity and specificity of DTS for detection of consolidation was comparable to DR and DES-DR. DES-DR performed better than DR in detection of nodules and cavitation. DTS was also able to detect centrilobular nodules with sensitivity and specificity of 57.4% and 86.5% respectively. Conclusion: DTS and DES-DR perform better

Tuberculosis (TB) is the most common opportunistic infection and the leading cause of death in HIV-positive people worldwide. Diagnosing TB is difficult, and is more challenging in resource-scarce settings where culture-based diagnostic methods rely on poorly sensitive smear microscopy by Ziehl-Neelsen stain (ZN). We performed a cross-sectional study examining the diagnostic utility of Microscopic Observation Drug Susceptibility liquid culture (MODS) versus traditional Ziehl-Neelsen staining (ZN) and Lowenstein Jensen culture (LJ) of pulmonary tuberculosis (TB) and multidrug-resistant tuberculosis (MDRTB) in HIV-infected patients in Bolivia. For sputum scarce individuals we assessed the value of the string test and induced sputum for TB diagnosis. The presence of Mycobacterium tuberculosis (Mtb) in the sputum of 107 HIV-positive patients was evaluated by ZN, LJ, and MODS. Gastric secretion samples obtained by the string test were evaluated by MODS in 102 patients. The TB-HIV co-infection rate of HIV patients with respiratory symptoms by sputum sample was 45 % (48/107); 46/48 (96 %) were positive by MODS, 38/48 (79 %) by LJ, and 30/48 (63 %) by ZN. The rate of MDRTB was 9 % (4/48). Median time to positive culture was 10 days by MODS versus 34 days by LJ (p Bolivia.

Tuberculosis associated factors caused by Mycobacterium tuberculosis of the RDRio genotype

Eloise Brasil Moraes

Full Text Available BACKGROUND Tuberculosis (TB continues to be a disease that affects many countries around the world, including Brazil. Recently, a subtype of Latin American-Mediterranean family strain was identified and characterised by RDRio. The strain has been associated with different characteristics of the disease. OBJECTIVES In the present study we investigated the association of epidemiological, clinical, radiological and bacteriological variables with pulmonary tuberculosis caused by RDRioMycobacterium tuberculosis strain in large regions of São Paulo. METHODS We conducted a cross-sectional study in 530 patients with pulmonary tuberculosis, diagnosed using sputum culture, from two regions of the São Paulo state in Brazil. The samples were brought to São Paulo reference laboratories for epidemiological, clinical, radiological and bacteriological analyses, and the data were obtained from a TB notification system. RDRio genotyping and Spoligotyping of the samples were performed. For the analysis of the categorical variables we used the chi-square test or the Fisher’s exact test, and for the continuous variables, the Mann-Whitney test. In addition, a logistic regression was used for multivariate analysis. Differences with p < 0.05 were considered significant. FINDINGS The RDRio deletion was identified in 152 (28.7% samples. In the univariate analysis, both the age groups above 25 years and alcohol consumption were associated with the RDRio deletion. The multivariate analysis confirmed the association of the RDRio deletion with the age groups: 25-35 years old [OR: 2.28 (1.02-5.07; p = 0.04] and 36-60 years old (OR: 2.36 (1.11-5.05; p = 0.03], and also with alcohol consumption [OR: 1.63 (1.05-2.54; p = 0,03]. MAIN CONCLUSIONS In this study, we identified new factors associated with the M. tuberculosis of the RDRio deletion strains infection.

Full Text Available Vast majority of active tuberculosis patients seeks treatment, do so promptly, still many patients spend a great deal of time and money “shopping for health” and too often they do not receive either accurate diagnosis or effective treatment, despite spending considerable resources. Objective: To find out the time taken to, for diagnosis of tuberculosis and to put patient on DOTS from the onset of symptoms and pattern of health seeking behavior of new pulmonary tuberculosis patients. A cross-sectional rapid assessment using qualitative (FGD and quantitative (Interview methods conducted at DOTS center of tertiary care hospital from rural Wardha. Participants: 53 pulmonary tuberculosis patients already on DOTS, in intensive phase. Main outcome measure: Delay in initiation of DOTS & health seeking behavior Results: Median total delay for starting DOTS was 111 days, (range: 10 to 321 days. Patient delay was more than provider delay. Patients delay was more in patients above 60 years, illiterate, per-capita income below 650 Rupees and HIV TB co-infection. Pattern of health seeking behavior was complex. Family physician was the preferred health care provider. Patient visited on an average four providers and spent around 1450 rupees (only direct cost before DOTS begin. Time taken from the onset of symptoms and start of DOT is a cause of concern for the tuberculosis control program. Early case detection is important rather than mere achieving target of 70% new case detection. Program manager needs to implement locally relevant & focused strategies for early case detection to improve the treatment success, especially in rural area of India.

2014-01-01

Full Text Available Background: Tuberculosis (TB is still a major worldwide concern. There is no pathognomonic clinical feature or imaging findings for definite diagnosis of extra pulmonary TB. Therefore, TB involvement of Gastrointestinal or Genitourinary tract can be easily confused with peritoneal carcinomatosis and advanced ovarian carcinoma. Our aim is to emphasize the importance of considering the disease based upon the epidemiologic clues of the patients, while interpreting the positive results for a suspicious ovarian malignancy. Cases: This paper illustrates 8 cases of ovarian or peritoneal tuberculosis, whose initial diagnoses were malignant processes of the GU tract. Conclusion: Tuberculosis ( TB should be always being considered in the differential diagnosis of advanced ovarian cancer, especially in the regions that are endemic for the disease.

Full Text Available Introduction: Acute epiglottitis is a relatively uncommon disease in both children and adults. It can be a serious life threatening disease because of its potential for sudden upper airway obstruction. Objective: To determine the prevalence of acute epiglottitis and to find out its association with Pulmonary Tuberculosis. Methods: All cases of acute epiglottitis admitted in ENT and Head and Neck Surgery ward of TUTH, Kathmandu, Nepal, from April 2001 to September 2007, were enrolled. Routine investigations including x-rays and blood cultures were done. The patients were further investigated to rule out the presence of Pulmonary Tuberculosis.The standard treatment protocol we used included Injection Ampicillin 500 mg intravenously six hourly for 72 hours followed by oral Ampicillin 500mg for 7 days, with analgesics and intravenous steroid (Hydrocortisone 200mg if required. Study Design: Prospective longitudinal study. Results: Majority of the patients presented with a history sore throat (83.3%, dysphagia (78.6% and odynophagia (78.6%. On examination all the patients were found to have swollen and congested epiglottis. Positive "Thumb sign" on plain X-ray soft tissue neck lateral view was found in almost all the patients (95.2%. Four patients presented with stridor and patient needed emergency tracheostomy. None of the investigations done to detect Pulmonary Tuberculosis was found to be positive. Conclusion: Acute epiglottitis is a rare disease which now occurs more commonly in adults. The annual prevalence of Acute Epiglottitis in adult in TUTH is 4.8 per 1000. This study did not find any association of acute epiglottitis with pulmonary tuberculosis.

Full Text Available Trace elements play an important role in tuberculosis infection because their deficiencies can be associated with impaired immunity. Blood samples were collected from a total of 320 active pulmonary tuberculosis patients and healthy individuals. The serum concentrations of Zinc, Iron, Copper, Calcium, lead, Arsenic and Selenium were analyzed by atomic absorption spectrometry. The levels of trace elements were measured after 2, 4 and 6 months of anti-TB treatment initiation in TB infected groups. Compared to the control group, the concentrations of Zinc, Selenium, and Iron were significantly lower (P< 0.001 in tuberculosis patients; however, that of Arsenic, Lead, and copper was significantly higher (P< 0.001 in the serum of patients. Cu/Zn and Cu/Se ratios were also significantly higher (P< 0.001 in TB patients compared to the control group. In addition, serum concentration calcium was similar in both TB patients and healthy controls. Our results indicated that trace elements concentrations in tuberculosis patients are related to each element role in immune system. Wherever the element is essential for the pathogenesis of bacteria, its concentration will remain low; and contrariwise, when the element is toxic for the bacteria, its level will be regulated up to provide a perfect condition for bacterial growth.

A total of 42 cases of newly diagnosed patients of cutaneous tuberculosis attending dermatology out patient department over a period of 1 year were included in the study. A detailed clinical examination and investigations including histopathological examination were carried out. Scrofuloderma was the most common form seen in 50% cases followed by lupus vulgaris in 42.86%, tuberculosis verrucosa cutis in 4.76%, and lichen scrofulosorum in 2.38% cases. The Mantoux test was positive in 83.33% cases. Characteristic tuberculoid granulomas were seen in 72.22% cases of lupus vulgaris, 42.86% cases of scrofuloderma and all cases of tuberculosis verrucosa cutis and lichen scrofulosorum. Cutaneous tuberculosis is still highly prevalent in upper Assam. Early diagnosis and treatment are essential to prevent its complications.

It is unclear whether patients with liver cirrhosis and coal miners with pneumoconiosis are at increased risk of developing pulmonary tuberculosis (TB). Furthermore, little is known of the likelihood of pneumonia in patients with bronchiectasis, haemodialysis, diabetes mellitus or advanced lung cancer being due to TB. To answer these questions, patients with these clinical comorbidities were analysed. The study was retrospective and included 264 TB patients, 478 non-TB pneumonia patients, and as negative controls, 438 subjects without pneumonia. The parameters analysed were age, gender and the presence of pneumoconiosis, bronchiectasis, liver cirrhosis, haemodialysis, diabetes mellitus and advanced lung cancer. Male gender was the only significant factor increasing the risk of pulmonary TB. When compared with non-TB pneumonia and control patients, the odds ratios were 1.862 and 2.182, respectively. Patients with liver cirrhosis did not show an increased risk of pulmonary TB after regression analysis. Pneumoconiosis resulted in a 2.260 (P = 0.003) odds ratio for pulmonary TB, compared with the controls. However, there was no difference in pneurmoconiosis between TB and non-TB pneumonia patients. Patients with bronchiectasis, lung cancer and those receiving haemodialysis had a lower risk for pulmonary TB in lower respiratory tract infection, with odds ratios of 0.342, 0.311 and 0.182, respectively. Physicians should first consider non-TB bacterial infection rather than Mycobacterium tuberculosis infection in pneumonia in patients with bronchiectasis, lung cancer or those receiving haemodialysis.

Pulmonary tuberculosis of occupational origin in a funeral director: A case report

Full Text Available In Poland the incidence rate of tuberculosis is higher than the average for countries of the European Union, Norway or Iceland. On the other hand, occupational tuberculosis is still rarely recognized in our country. In this paper we present the first in Poland- to our best knowledge - case of pulmonary manifestation of this disease acquired at work in a funeral director. The recognition of the occupational etiology of the discussed illness gave rise to an array of diagnostic problems and became feasible after a thorough analysis of the patient's history and literature data, which allowed finding the relationship between infection and performed job. We speculated that the transfer of the dead body and handling of cadavers may expel residual air from the lungs of the deceased. Although tuberculosis occurs frequently in the general population, the recognition of work-related cases of this disease is still rare, especially among funeral directors. Med Pr 2014;65(3:429–435

Tuberculosis is a common and potentially deadly infectious disease, usually affecting the respiratory system and causing the sound properties of symptomatic infected lungs to differ from non-infected lungs. Auscultation is often ruled out as a reliable diagnostic technique for TB due to the random distribution of the infection and the varying severity of damage to the lungs. However, advancements in signal processing techniques for respiratory sounds can improve the potential of auscultation far beyond the capabilities of the conventional mechanical stethoscope. Though computer-based signal analysis of respiratory sounds has produced a significant body of research, there have not been any recent investigations into the computer-aided analysis of lung sounds associated with pulmonary Tuberculosis (TB), despite the severity of the disease in many countries. In this paper, respiratory sounds were recorded from 14 locations around the posterior and anterior chest walls of healthy volunteers and patients infected with pulmonary TB. The most significant signal features in both the time and frequency domains associated with the presence of TB, were identified by using the statistical overlap factor (SOF). These features were then employed to train a neural network to automatically classify the auscultation recordings into their respective healthy or TB-origin categories. The neural network yielded a diagnostic accuracy of 73%, but it is believed that automated filtering of the noise in the clinics, more training samples and perhaps other signal processing methods can improve the results of future studies. This work demonstrates the potential of computer-aided auscultation as an aid for the diagnosis and treatment of TB.

Background Determination of disease activity of chronic destructive pulmonary tuberculosis (TB) on imaging studies can be difficult because several imaging findings due to disease chronicity such as a residual cavity can be misinterpreted as an active disease. Purpose To evaluate computed tomography (CT) findings to predict active disease in patients with chronic destructive pulmonary TB. Material and Methods CT findings of 36 patients with chronic active destructive pulmonary TB and 78 patients with chronic inactive destructive pulmonary TB were reviewed and their patterns of lung lesions were compared. Statistical comparisons were performed using chi-square and Student's T tests for univariate analyses, and a stepwise logistic regression method was used for multivariate analysis. Results Based on univariate analyses, cavitary destruction (P = 0.015), non-branching centrilobular nodules (P < 0.001), tree-in-bud pattern (P < 0.001), airspace nodules (P < 0.001), and cavities in other lobes (P = 0.001) were more frequently seen in chronic active destructive pulmonary TB. A stepwise logistic regression analysis demonstrated that tree-in-bud pattern (odds ratio, 52.3; 95% confidence interval, 6.2-437.2; P < 0.001) were significant CT findings associated with active disease. Conclusion Tree-in-bud pattern were the most characteristic CT findings to predict active disease in patients with chronic destructive pulmonary TB.
